Description Laurence Withers 2005-12-26 10:03:20 UTC

Hi, I have a valid C++ program which crashes gcc-3.4.4-r1; I'll attach the preprocessed source. It does this even when specifying no cflags, i.e. "g++ crash.ii" will crash with a segfault.

I'll also attach my make.conf and emerge info, in case it helps.

Oops, source was bzip2'd since it's too large to upload otherwise. Apologies.

Reopening since source now provided in a format that can be understood :-)

post the actual code which is causing the failure, stripped down if possible

you also didnt post the actual error message ...

Actually, a reboot has fixed the problem. This is very strange, as it was consistently crashing on just that one program, and no others, even though the others used exactly the same libraries and so on.
