[Bug c++/24605] [4.0/4.1 Regression] internal compiler error: Segmentation fault while compiling c++ file
--- Comment #19 from bangerth at dealii dot org 2006-10-12 01:06 --- 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...

--- Comment #18 from jason at gcc dot gnu dot org 2006-07-05 18:03 --- 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. -- jason at gcc dot gnu dot org changed: What|Removed |Added Summary|[4.0/4.1/4.2 Regression]|[4.0/4.1 Regression] |internal compiler error:|internal compiler error: |Segmentation fault while|Segmentation fault while |compiling c++ file |compiling c++ file http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24605

--- Comment #9 from janis at gcc dot gnu dot org 2005-11-10 21:22 --- 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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24605

(In reply to comment #5)
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::ucPtrT::operator T*() const'
C:/rah/Vc/CppLib/RefCntUtil.h:101: error: conflicts with previous declaration
`RefCntUtil::ucPtrT::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.
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

--- Comment #6 from janis at gcc dot gnu dot org 2005-11-05 01:31 --- 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.
