Description Derek Dolney 2004-10-21 18:42:16 UTC 
If I compile libvorbis with -Os, oggenc (from vorbis-tools) segfaults. -O2 works fine.

Portage 2.0.51 (default-linux/x86/2004.3, gcc-3.4.2, glibc-2.3.4.20041006-r0, 2.6.9-gentoo-r1 i686)

Comment 1 Derek Dolney 2004-10-21 18:52:02 UTC 
Oops, I should have said I'm using libvorbis-1.1.0 and vorbis-tools-1.0.1.
Comment 2 Jeremy Huddleston (RETIRED) gentoo-dev 2004-10-21 22:39:44 UTC 
is there any chance you have a gcc-3.3 installed to test if it's specific to 3.4?
Comment 3 Derek Dolney 2004-10-22 08:14:16 UTC 
OK, I checked, and this is gcc-3.4 specific. gcc-3.3.4 works fine with -Os, but gcc-3.4.2 results in segfaults.
Comment 4 Jeremy Huddleston (RETIRED) gentoo-dev 2004-10-22 10:59:13 UTC 
ok... -Os is replaced with -O2 for 3.4 versions of gcc
