I still got no results from gdb, but let me say the problem doesn't happen in
curl 7.10.1 installed in Red Hat Linux 7.3 (gcc 2.96, glibc 2.2.5), neither in
Solaris 2.8 (gcc 2.95.3 20010315, SUN libc). I only have it in Red Hat 8.0
(gcc 3.2 , glibc 2.2.93). I beleive the problem hasn't hit a lot of people
since many hadn't have a chance to upgrade to redhat 8.0 ;-)
