This is where SIGILL actually happens (this is the firewall function in
libc, sysdeps/mach/hurd/i386/trampoline.c). Do you have the libc0.3-dbg
package installed? it's odd we don't have debugging signals. Anyway, the
offset seems to be 0x13da000, thus the functions below.

I don't know _hurd_setup_sighandler very much and don't have time to
dive in it, but that's most probably where to look at. Just an idea: is
guile perhaps using SA_ONSTACK? It's not yet supported, we are still
waiting for moving the threadvars into TLS before enabling it.
