Re: pkg/52705: www/seamonkey crashes on i386 when built with -march=prescott

Yes, it does.
A small correction:
When I talk about CFLAGS, I mean CFLAGS and CXXFLAGS, e.g. when I include in
both -march=prescott, seamonkey core-dumps.
Note, I also deleted the .mozilla directory just to be on the save side.

I didn't send any stack trace as I'm puzzled how to generate a usable one, e.g.
one with symbolic names.
For below output, I had this in mk.conf:
CFLAGS= -O0 -g -march=prescott -pipe
CXXFLAGS= -O0 -g -march=prescott -pipe
INSTALL_UNSTRIPPED= yes
