OS X 10.6: PARI-2.5.3 gp-dyn GCC-4.6.3 -O0 SIGSEGV

[Jeroen Demeyer <jdemeyer@cage.ugent.be>]

I get a segmentation fault
on Mac OS X 10.6
running gp-dyn
from PARI-2.5.3
compiled using GCC-4.6.3
with the -O0 option
executing factor(10356613*10694706299664611221)

This is probably not PARI's fault, but I thought I should report it
anyway. Is this a known problem? Interestingly, the problem seems to be
related to dynamic linking, it does not occur with gp-sta. PARI/GP was
configured with:
$ export CFLAGS="-O0"
$ ./Configure --without-gmp --without-readline


gdb backtrace:
