Build 2.3 or 2.3.1 on linux with the following
configure command:

./configure --enable-shared --without-threads

Try running the rlcompleter example.  If you hit TAB
with completions enabled, you'll get a core dump after
you hit return on that line.  Works fine if I build
with threads enabled.  

This is a major problem for me since we have to deliver
our software on machines that do not support pthreads
(hpux 10.2 for example).

Assuming the problem is just a shallow one, would the
following patch "fix" the problem?

It makes the crashes go away for me.

This seems to have been fixed, at some indeterminate time in the past.
