I was just hit *hard* by this issue (in an extension that worked 
perfectly well under all test cases, and all but one demo script,
which happened to be the only one that happened to do a certain
trivial operation more than 222 times), so I added a FAQ entry:

http://effbot.org/pyfaq/why-does-my-c-extension-suddenly-crash-under-2.5.htm

feel free to add symptoms or other observations for other platforms 
and/or extensions.
