Oh goody. Can you kill -SEGV or something the python process and post
(or send me, if it's really huge) the backtrace? Also, it might be an
idea to do look at the stack trace a few times to check that we don't
have a memory scribbling type bug.
If you're really feeling keen, you could send me the config.h your
readline made when you configured it...

Well, obviously not, but when mystery-bug hunting all information is
good. Anyway, from what Quinn said, I bet your problem would go away
Fun fun fun.
I have a cat, so I know that when she digs her very sharp claws into
my chest or stomach it's really a sign of affection, but I don't see
any reason for programming languages to show affection with pain.
