Some of this functions in current cvs. Dunno about this specific case.
In no compiler do we properly follow the Alpha ABI wrt complex numbers.
There is no ETA for this either.

Thanks, this is a known problem in the compiler. I thought it was
fixed, but apparantely I dreamt. Please feel free to report this to

>Description:
Attempting to read anything from an istream causes a segmentation fault. I have traced the problem to line 326 in file locale_facets.h:
bool
is(mask __m, char __c) const throw()
-> { return _M_table[(unsigned char)(__c)] & __m; }
It appears that _M_table = 0x0.
I am using a local installed version of stdlibc++-2.90.7, compiled with gcc 2.95.2. The test code (see How-To-Repeat) was compiled and linked using the -static flag. Both debug (-g) and optimised (-O3) compilation show the same bug.
As a side note, compiling the same code with 2.90.6 runs fine - but 2.90.6 float/double output doesn't work, and so I need 2.90.7.
>How-To-Repeat:
#include <iostream>
#include <fstream>
int main()
{
int n; // replace with your favorite type
cin>>n; // boom!
ifstream is("test.dat");
is>>n; // still boom!
return 0;
}

When using 'mode' argument in ofstream
e.g. ofstream f("tm", ios::bin);
mode bit 'ios::out' gets cleaned so you have to type
ofstream f("tm", ios::out|ios::bin);
The same problem with ifstream.

place
'mode |= ios::in;' in ifstream::ifstream(...)
and
'mode |= ios::out;' in ofstream::ofstream(...)

Changes in unrelated areas of my code would may the
problem go away or reappear, e.g., just commenting a

I can provide code if necessary, but it seems odd that
bastring.h includes bastring.cc, so I'll assume this is
an oversight.

>Description:
When compiling a 32 bit app to use 64 bit file offsets (largefiles) one defines _FILE_OFFSET_BITS=64 before including system headers. This causes, I believe, 'open' to be redifined to 'open64' so that one picks up the correct library function. However, if one happens to include streambuf.h from the STL this undefs 'open' and stops this working. This doesn't happen with the Sun compiler since they use some #pragma mechanism instead.

Coredumps occur after doing a D.pop_back() on an

After quickly reading it, I can only surmize that
stl_deque.h's class deque's pop_back() mutator
properly doesn't check to see if the object is empty.
(I didn't fully understand pop_back_aux(), but it may
be pointless to go into that function if we're empty.)
Note: I did a search for pop on libstdc++ and didn't
see a report for this bug. I think it's a major one,
so I hope we can fix it soon. Thanks for the work!

>Description:
First, I hope this is the correct place to report an STL
in gcc 2.95.2. If not, please let me know who to contact.
Resizing a valarray of valarrays can cause a segmentation
fault under certain circumstances.
I am very new to using the STL, and to C++ in general. This
is the first large program I have written using the STL, so
this could well be a feature and not a bug. :) However, it
looks like a bug to me, and I can't figure out a reason why
it would occur othersize, so I'm reporting it to the list.
Let me know if you need more information, or if I should
redirect this report to someone else.
>How-To-Repeat:
A test program is included, which should reproduce the
crash. I've also included tha Makefile, so you can see the
(simple) command line switches I used, and a backtrace, in
case that is helpful.
To reproduce the core dump:
1. Define a valarray<valarray<double>>. (I believe it
also works with types other than double, but I haven't
thoroughly tested any other types.)
2. Resize the valarray to some size, say 10.
3. Resize any of the elements of valarray to another size.
(element 5 is resized to size 2 here, but any valarray
element to any size seems to work.)
4. Resize the valarray again, to the _same_ size as
previously. (10 in the case of this example.)
The core dump should occur at this point.
The second resizing of the main valarray must be to the same
size as it was originally set to... if it is set with
resize(9) or resize(11) in this case, rather than
resize(10), no crash occurs.

--------
#include <valarray>

because:
26.1/1
The complex and valarray components are parameterized by the type of
information they contain and manipulate. A C++ program shall
instantiate these components only with a type T that satisfies the
following requirements
[...]
-- If T is a class, its assignment operator, copy and default
constructors, and destructor shall correspond to each other in the
following sense: Initialization of raw storage using the default
constructor, followed by assignment, is semantically equivalent to
initialization of raw storage using the copy constructor. [...]
valarrays do not meet this requirement.
If you want to build a two dimensional array out of valarray, please
consider using gslice and gslice_array in conjunction with a plain
valarray.

>Description:
A bug using STL library in MultiThreading.
The std::string is not ReEnterant !
In Release 2.95.1
It cause many Segmentation calls in our programs.
I replaced the STL header files with the ones from SGI,
and the problem was fixed.

>Description:
from stl_multiset.h:
typedef typename _Rep_type::const_reverse_iterator reverse_iterator;
typedef typename _Rep_type::const_reverse_iterator const_reverse_iterator;
stl_set.h is the same.
I believe the first one of the pair should be _Rep_type::reverse_iterator.
>How-To-Repeat:
#include <multiset.h>
class X
{
public:
int x;
int GetX();
};
typedef multiset<X> XSet;
typedef XSet::reverse_iterator XIterator;
int main()
{
XSet a;
XIterator b;
for (b = a.rbegin(); b != a.rend(); b++) {
cout << b->GetX();
}
}
results in
passing `const X' as `this' argument of `int X::GetX()' discards qualifiers

Can I remove this one? About fifteen minutes after I sent it, the
light dawned, and then I found some documentation about it. (Blush).

>Description:
I am generating two related errors concerning a global variable
that instantiates the map template class.
When attempting to access the variable from a function, I am
able to access and change keys that were generated in the
calling function as I expect. However, the calling function
is not able to access keys created in the called function.
When attempting to access the variable from code in a second
file none of the keys belonging to the map variable are
available to me. None of the keys generated in this file
are available in the calling function in the main file.
>How-To-Repeat:
The files I am attaching contain a short code snippet to repeat
the error. (If the file does not get to you, please get it
from http://www.tiki-lounge.com/~toshio/map-test.tgz )
Files: map-test.cpp: The file containing the main function.
map-test.h: Contains an extern definition for the
global map variable.
map-extern.cpp:Contains another function that attempts
to use the global map variable.
t: Contains output from the program run.
Compile, link, and run to regenerate the error.
>Fix:
Unknown. If this is just my misunderstanding of the
spec or if this is an error in gcc/egcs rather than
libstdc++, please let me know.

>Description:
The basic_string<> class uses asm() in its release() method
for the Rep structure. This causes a compilation error
when compiling with the GCC -fcheck-memory-usage option.
>How-To-Repeat:
Compile the above program with the option -fcheck-memory-usage.
>Fix:
I could discover no easy workaround. I would assume that
it would be possible to move the asm() statement in this
function to another file and mark that with
__attribute__ ((no_check_memory_usage)), but I don't know
anything about x86 assembly language.
iostream.h and stl_alloc.h also have assembly language in them.
