Summary: <string>.join(generator) crash bug
Initial Comment:
Reproduced on Windows XP (Python 2.2b1) and Redhat
7.1 (Python 2.2b1). Bug didn't manifest with Python
2.1 (WinNT4) or Python 2.2a2 (RH7.1).
Some generators crash the interpreter when used with
<string>.join(generator). The same generators work
fine when used with for-loops or with the build-in
function list.
I couldn't create a more simple generator that would
cause the interpreter to crash, so I'll attach the
whole script (longish).

Hmm (Guido). tuple resizing could be relevant, but
reverting to 2.61 of tupleobject.c didn't yield a crash.

I can reproduce a crash under 2.2b1 and 2.2b2, but not
under current CVS Python. This irks me, because I don't
know of anything relevant that changed (that is, AFAICT
it's "working" by accident now -- or never should have
failed). I'll rebuild 2.2b2 from scratch and dig into it.

I think I *just* fixed this. Can you try a recent CVS?
tupleobject.c 2.62.
