When running btdownload* or btlaunchmany*, python dies with the following message just after or during checking existing file integrity: python: stack smashing attack in function fast_function() Exact timing is somewhat random, sometimes it runs longer than other times. I'm running python 2.3.3-r1 and bittornado 0.3.4. Also tried with python 2.3.4, with the same result. Trying with bittornado 0.3.7 gives somewhat different results. Now, it always seems to finish the entire file integrity check, and the abort happens when it starts connecting to peers. Also, the message is different: python: stack smashing attack in function call_function() Note that this is similar to bug #59603 (bittorrent), so it's probably due to something in the shared codebase (AFAIR bittornado is derived from bittorrent). Perhaps this bug should also be filed against python; IMHO programs written in python shouldn't be able to trigger stack smashing in the interpreter.
