Okay, I'll try to do that this weekend.

This is interesting.  I get the same crash from the already-built
clisp binaries on both Fedora 15 and Fedora Rawhide.  Somehow those
binaries were built without the crash happening at build time, though.
 After buildilng with debug turned on, here's the first part of the
backtrace:

(gdb) bt

Hmmmmm, and we got a new glibc on June 3 (Fedora 15) / June 7
(Rawhide).  It looks like there might be something wrong with the new
one.  If I can come up with some C code that produces the same crash,
I'll file a bug report.

I think I see what's going on here.  I attempted to build against
readline 5 to avoid the license problems with linking clisp against
readline 6.  It appears I bungled the job.  I'll try again.

Thanks for your reply.
