Bug 27638 – Emerging gcc-3.2.3-r1 causes segfault

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Jaakko Holster 2003-08-31 03:06:26 UTC]

When I try to upgrade gcc 3.2.2 -> 3.2.3-r1 by 'emerge -u system', compilation causes a 
segfault.

Try without '-pipe' in C[XX]FLAGS, and please include info from 'emerge info'.

[Comment 3 Jaakko Holster 2003-09-02 13:14:53 UTC]

Thanks Martin. It compiled successfully without '-pipe'. I also dropped out 
'-fomit-frame-pointer' flag, thus I'm not sure which one caused the segfault. Anyway, 
this item can be marked as solved. 
 
Just for info: 
 
Failed flags: 
CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer" 
 
Ok flags: 
CFLAGS="-march=athlon-xp -O3"

dropping CFLAGS
