Summary: 2.0: cum sympt; w/gdb bktr; OBSD2.8.
Initial Comment:
Reverted to Python 2.0 + all patches on patch pages,
still with OpenBSD 2.8. Only non-default module set is
zlib (needed for Mojo Nation according to the docs).
System is Pentium 133MHz.
Ok, I'm getting better at this now. This time, I ran
GDB on it, since I noticed that one of the bugs may
have cumulative dependent symptoms. Also, I'm typing
this bug report into the web browser so that it wraps
correctly (I'll cross my fingers that it doesn't crash
though; that's why I prefer Emacs; I suppose I could
try SSL W3 Emacs but that is hard; not now.)
Here is the gdb output where it did die:

Once again, I will attach the config.* (config.cache,
etc.) to this in a file.

There is a known bug on some BSD variants that causes
problems when mixing both the threaded and the nonthreaded
libc. So unless it can be established that this is not the
cause, or unless other information on this bug becomes
available, I close this as "won't fix".

Without access to an OpenBSD machine, this is difficult to
analyze. I agree with Jeremy that it looks like a bug in
your C library and/or operating system, and I also
recommend to build Python with --disable-threads.

To me, this likes like a bug in the multithread support of
your operating system. To work around this bug, you should
configure python with --disable-threads.
