All my perl programs just started dying with "Illegal instruction". I upgraded some gnome packages with Ximian on RH8, and I have done my best to find what dependencies were screwed up, but I can't find any. With strace I see it load all its libraries and it looks fine up to the first attempt to read the perl script, which returns the illegal instruction. In gdb, I get 
Program received signal SIGILL, Illegal instruction.
Switching to Thread 8192 (LWP 20089)
0x0804b3c0 in ?? ()
(gdb) bt
#0  0x0804b3c0 in ?? ()
#1  0x400b92cc in Perl_pop_scope () from /usr/lib/perl5/5.8.0/i386-linux-thread-multi/CORE/libperl.so
etc...
How can I find the problem?
