More tests. (*) What is the output of signal.getsignal(signal.SIGUSR1) before importing faulthandler (before calling any faulthandler method)? Example: $ python3 Python 3.7.3 (default, May 11 2019, 00:38:04) >>> import signal; signal.getsignal(signal.SIGUSR1) <Handlers.SIG_DFL: 0> (*) Can you try to run attached script in gdb? If you get a crash, type "where" to get the traceback. Example: $ gdb -args ./python script.py (gdb) handle SIGUSR1 nostop Signal Stop Print Pass to program Description SIGUSR1 No Yes Yes User defined signal 1 (gdb) run Starting program: /home/vstinner/python/master/python script.py Program received signal SIGUSR1, User defined signal 1.
