Yes.  Now I'm using Fedora Core 2, but Red Hat 9 back then, I think.

I just found some time for some more testing, and it's FC2's noexecstack
messing up in this particular case.  If I create, using gcc 2.95.3 and
glibc 2.1.3 vanilla, a static ARM little-endian "Hello world" binary, and
run it with qemu-arm latest CVS, it works if I specify -Wl,-z,execstack
when linking qemu-arm, and crashes with sig11 if I do not.
