The bad news: I've found another reproducible core-dump bug in
Python-2.0 under Linux. Actually I found it in 1.5.2 while making
some changes to CML2, and just verified that the CVS snapshot of
Python 2.0 bombs identically.
The bad news II: it really seems to be in the Python core, not one of
the extensions like Tkinter. My curses and Tk front ends both
segfault in the same place, the guard of an innocuous-looking if
statement.
The good news: the patch to go from code-that-runs to code-that-bombs
is pretty small and clean. I suspect anybody who really knows the ceval
internals will be able to use it to nail this bug fairly quickly.
Damn, seems like I found the core dump in Pickle just yesterday. This
is getting to be a habit I don't enjoy much :-(.
I'm putting together a demonstration package now. Stay tuned; I'll
ship it tonight.
