>Description:
I believe I've found an error in the thread management in std::string in
the library. Basically, the problem occurs in the following context:
- There is a global variable declared:
std::string s ;
This variable is initialised by reading from a configuration file,
in main, before any threads have been initialized. It is non-const
so that this initialization can occur; it is never modified
afterwards. Since it is never modified once threads have been
started, no accesses are protected by mutex's or anything else.
- A copy of this variable is made to another string variable. This
causes the reference count _M_references in basic_string::_Rep to
become 1, with the result that _Rep::_M_is_shared will return true.
- Several threads are started. At exactly the same moment, in thread
A and thread B, an expression along the lines of "s[ i ] == 'x'" is
executed.
Note that because the instance is not const, the function called is
the non-const version of basic_string::operator[], even though
nobody is going to modify anything. (And because nobody is modifying
the string in any of the threads, there are no locks.) This function
begins by calling _M_leak; since _Rep isn't yet leaked, this
function calls _M_leak_hard, and since the _Rep is shared, we end up
in _M_mutate. _M_mutate, after calculating a lot of different sizes
(which aren't really relevant here), executes an if, which evaluates
true. The last two lines of the if are the critical section:
imagine that thread A has been executing up until now, and it is
interrupted by thread B. At this point, thread A has not modified
anything in the actual object -- it has made a series of tests,
decided that it must isolate the representation, and has prepared a
new representation, but it has not started installing it. Thread B
executes the same code, and since the actual object has not been
changed, comes to the same conclusions, and arrives at the same
point. From this point, several scenarios are possible: thread B
continues, calling dispose on the _Rep in the actual object (which,
since there is still another object using it, will not be
destructed), installs its own newly created _Rep and returns a
reference to the data in it. At this point, thread A takes over
again, calls _M_rep()->_M_dispose, which disposes of the _Rep
thread B has just installed -- since the just installed _Rep is not
shared it is deleted, and the reference in B is invalid.
For the moment, I'm not convinced that a copy on write implementation of
the std::string interface is possible with only the primitives
atomic_incr, atomic_decr, barrier_read and barrier_write -- the current
g++ implementation tries to do it with even less. (Note that the
current implementation fails lamentably in a multi-processor
environment; there is no effort what so ever made to ensure that writes
are actually seen by the other processes. But I've not much experience
in evaluating this sort of problem.)
Might I suggest that the current implementation be completely scrapped,
in favor of a simple deep copy. The results will be somewhat slower,
but at least they will work. Alternatively, if you have some mechanism
of switching implementations depending on the -mt switch of the
compiler... (I've found COW to be a definite win in my single threaded
applications.)

Dear Fred,
Are you protected your string access (both read and write) with mutex
protection?

We are having some crashes with stdc++. It happens on
a 2-processor i686 machine - the crashes went away if
we boot the same machine with only one processor.
Also, core dumps only happen under heavy loads - no
crashes if the threads are not many.
The core dumps scatters over a handful of places - in
std::string, std::basic_string<wchar_t>, std::map,
std::_Rb_tree, std::__default_alloc_template,
std::pair, std::_List_base, std::_Rb_tree_rebalance,
std::_Rb_tree_rotate_left, etc.
The os is Redhat Linux 7.3, The version we have are
compat-libstdc++-6.2-2.9.0.16
libstdc++3-3.0.4-1
libstdc++-2.96-113
libc-2.2.5-43
glibc-common-2.2.5-43

And I have more.
The software was build with gcc 3.0.2.
Any ideas?
Thanks!

We are having some similar crashes with stdc++. It happens on a 2-processor i686 machine - the crashes went away if we boot the same machine with only one processor. Also, core dumps only happen under heavy loads - no crashes if the threads are not many. The core dumps scatters over a handful of places - in std::string, std::basic_string<wchar_t>, std::map, std::_Rb_tree, std::__default_alloc_template, std::pair, std::_List_base, std::_Rb_tree_rebalance, std::_Rb_tree_rotate_left, etc. The os is Redhat Li nux 7.3, The version we have are compat-libstdc++-6.2-2.9.0.16
