Bugzilla Bug 68479

If I compile libvorbis with -Os, oggenc (from vorbis-tools) segfaults. -O2
works fine.

Oops, I should have said I'm using libvorbis-1.1.0 and vorbis-tools-1.0.1.

is there any chance you have a gcc-3.3 installed to test if it's specific to
3.4?

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.

ok... -Os is replaced with -O2 for 3.4 versions of gcc
