Primary combination: "-march=pentium4 -O3 ...",
minimal: "-O1 -march=i686 -msse -ftree-vectorize".
Rebuilding zlib v1.2.3 cause segfault on related apps (I use seamonkey, all
under gentoo). All other apps built on pentium4/O3/gcc4.3.3.

Please add "-mincoming-stack-boundary=2" to CFLAGS and report what you got.

No error.
Current i386.h must be fixed by hands. Next I attach gcc-4.4.1 version of this
patch.

Simplest way to save Bug 32893 solution: replace MAX_STACK_ALIGNMENT by
STACK_BOUNDARY in vect_can_force_dr_alignment_p (tree-vectorizer.c / ...). No
error more.
