Description Julioromano 2005-11-14 15:13:59 UTC

Tried with different 4.4.x and 5.0.x versions.
All versions do compile without errors, and when trying to run the /usr/bin/php
executable it quits with an Illegal Instruction message.
Strace reports exiting due to SIGILL.

My cflags are "-O2 -march=athlon-xp -pipe -fomit-frame-pointer -msse2 -mfpmath=sse"

Falling back from -msse2 to -msse solves the problem.

I thought -msse2 wasn't an aggressive cflag, isnt'it?

Reproducible: Always
