Extended Description

When I try llvmg++ on a code from C++ boost graph library, I get the following:

home/ghost/Work/boost/boost/random/linear_congruential.hpp:213: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://llvm.cs.uiuc.edu> for instructions.

The procesourced source code is available at http://zigzag.cs.msu.su/~ghost/dfs.ii

I believe that. Unfortunately our C++ front-end is pretty far out of date. The last time we sync'd up with CVS was Sep 24. If you find a GCC PR for this, it will probably indicate the patch that fixed it and we could arrange to pull it in...

Updating the C front-end to newer GCC CVS is definitely something we want to do, we just don't have the man-power for it right now...

Just a bit of additional info: regular gcc 3.4 from 2004-02-22 (Debian package) does not crash on that code, so maybe the bug was already fixed by that date.

This is a segfault in the non-LLVM-specific parts of the G++ parser, with this backtrace:

This will probably be fixed in the future by merging newer bits into the LLVM G++ front-end from GCC CVS, but until then there is nothing that we can really do about it.

Replicated the crash on powerpc-apple-darwin7.3.0. However, I don't seem to be getting a backtrace out of gdb today. Maybe my luck will be better next time. Marking this as crash-on-invalid because of the errors I get from cc1plus. Inquiring minds want to know -- what hardware platform are you using? (your bug report says "Other").
