FWIW, there is a caveat in the OpenBSD man page concerning the use of siglongjmp(): http://www.openbsd.org/cgi-bin/man.cgi?query=sigsetjmp&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=htm "Use of longjmp() or siglongjmp() from inside a signal handler is not as easy as it might seem. Generally speaking, all possible code paths between the setjmp() and longjmp() must be signal race safe, as discussed in signal(3). Furthermore, the code paths must not do resource management (such as open(2) or close(2)) without blocking the signal in question, or resources might be mismanaged. Obviously this makes longjmp() much less useful than previously thought." ---------- title: Display Python backtrace on SIGSEGV, SIGFPE and fatal error -> Display Python backtrace on SIGSEGV, SIGFPE and fatal error _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8863> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
