Hi, I pushed my faulthandler module into the default branch (Python 3.3). Since one week, I fixed a lot of bugs (platform issues), improved the tests and Antoine wrote a new implementation of dump_backtraces_later() using a thread (instead of SIGALRM+alarm()). It should now work on all platforms (but register() is not available on Windows). Use "python -X faulthandler" or "PYTHONFAULTHANDLER=1 python" to install the fault handler at startup (catch segfaults and other fatal errors). You can also register a signal (e.g. SIGUSR1) to dump the traceback on this signal. The latest added feature is to be able to the dump the traceback after a timeout and exit the process: we may use it on regrtest.py to learn more about test_multiprocess and test_threadsignals hangs. Issue #11393 has a patch implementing this issue: add --timeout option to regrtest.py. You can also just dump the traceback after the timeout without exiting. Py_FatalError() always print the Python traceback (except if an exception was raised: print the exception with its traceback). For more information, read the doc: http://docs.python.org/dev/library/faulthandler.html Please tell me if you have any issue related to faulthandler. -- If you get "undefined reference to `_PyFaulthandler_Init'" compiler error, copy Modules/Setup.dist to Modules/Setup (cp Modules/Setup.dist Modules/Setup). test_faulthandler hangs on AMD64 Gentoo Wide 3.x and AMD64 OpenIndiana 3.x. It looks to be related to the stack overflow test (the stack is maybe not limited on these buildbots?). I have a patch, but I cannot test it because these buildbots are dead (oops, sorry!). Most buildbots are red because a regression in test_logging (since 2 days): I disabled temporary the test (issue #11557), I hope that the situation will be better in a few hours. Thank you Antoine for your reviews! Victor

Could it be collapsed by default? It's quite long, and redundant with the sidebar. thanks Antoine.
