There is at least a 4.1 regression here as we ICE after an error.

------- Comment #5 from janis at gcc dot gnu dot org  2005-11-05 01:00 -------
I tried out a few cross compilers for i686-pc-cygwin over the last few
months.  The code compiled cleanly on 20040607.  Sometime between then
and 20040709 it started failing with a different ICE from what it gets now.
For awhile (at least from 20040921-20051127) it got only:

C:/rah/Vc/CppLib/RefCntUtil.h:119: error: declaration of
`RefCntUtil::ucPtr<T>::operator T*() const'
C:/rah/Vc/CppLib/RefCntUtil.h:101: error: conflicts with previous declaration
`RefCntUtil::ucPtr<T>::operator X*() const'

That error went away.  The current ICE and several of the other errors started
sometime between 20050227-20050404.  Here's a testcase for one of them:

class CloneableObject
{
  friend class CloneWalker;
public:
  virtual void WalkClone(CloneWalker&) const = 0;
};

class CloneWalker
{
  CloneWalker(int) {}
  CloneWalker(void) {}
};

It fails on powerpc-linux with "error: ‘CloneWalker’ has not been declared",
the first error that the large testcase gets, not the one that leads to
the ICE.

The submitter's testcase compiles cleanly with a i686-pc-cygwin cross
compiler using r92494 from 20041222.  It fails with lots of "uses anonymous
type" errors, but no ICE, with r92877 on 20050104.  I've got lots more builds
going to identify other ranges where changes happened.

There is a missing forward declaration for class CloneWalker in the supplied
test case (although I believe older versions of gcc did not require this).  I
have posted a revised test case where I added the declaration and fixed another
problem.  With this test case and gcc 4.1.0,

gcc -c  compiles
gcc -c -O2 gives a segmentation fault

If the forward declaration of class CloneWalker at line 50437 is commented out,
gcc -c (4.1.0) gives a number of error messages before

I can't reproduce the segfault using a cross compiler on a powerpc64-linux
system.  The second testcase compiles successfully there using several very
recent checkouts from the trunk, including the date the PR was filed.

Someone else will need to try this using a native i686-pc-cygwin compiler.

I tried this testcase at -O2 on an i686-pc-linux-gnu X sh-elf compiler,
build from r110809 4.1 branch sources.
The compilation succeeded, but only after taking considerable time and memory:

Are you sure you have enough virtual memory to compile this test case?

P.S.: top displayed 34% memory usage near the end of the compilation,
on a machine with 2 GB of RAM.

I just tried main branch r111111 and the test case compiled fine.  I have 2 GB
vm (and 2 GB ram) so I doubt the previous problem was vm exhaustion.  I don't
recall exactly what the vm use was with the segfaults but it wasn't alarming,
and the test case never exceeded 1 GB vm with r111111.  I would certainly hope
that gcc would politely report vm exhaustion as out-of-memory or some such
rather than segfaulting.

With the Intel Windows compiler I did have to turn off some optimization to
stay within the 2 GB vm limit on the "real" cases, but gcc -O2 handled them
with no problem.

Ron

That, unfortunately, is out of the hands of gcc: most operating systems allow
processes to allocate more memory than there physically is, on the assumption
that typically processes allocate more memory than they actually need, or that
the don't need it right away. Only when the process actually writes to a page
is it physically allocated. If at that time the operating system cannot honor
its commitment of providing a physical page for an allocated page, the
process segfaults. Since the OS typically doesn't provide a way to figure
out why the segfault happens, application programs don't usually have a way
to state the actual cause of the segfault.

All that said: does the problem persist? Could you repeat your tests with
the latest snapshots to see whether this still happens?

Thanks
  Wolfgang

Removing the 4.2 regression tag, since apparently it's fixed there.  I'm not
sure how this qualifies as a regression at all, since the bug was reported
against 3.4 and there's no report of it working better with a previous release.

Since this is solved on mainline and nobody seems to have been able to
ever reproduce it anyway, there doesn't seem to be a chance of this
being actively worked on on older release branches. I'll therefore close
it. We can always re-open it if someone can come up with a testcase
that reproducibly crashes...
