Antoine Pitrou <pit...@free.fr> added the comment: Perhaps you can compile and run this C program, before and after the system changes, and post the output:
#include <errno.h> #include <signal.h> #include <stdio.h> int main(int argc, char** argv) { sigset_t set; int i, ret; printf("NSIG = %d\n", NSIG); for (i = 1; i < NSIG; i++) { errno = 0; ret = sigaddset(&set, i); printf("sigaddset(%d) returned %d, errno =%d\n", i, ret, errno); } return 0; } (on Ubuntu 16.04, I get NSIG = 65, and all signal numbers work fine) ---------- nosy: +pitrou _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33329> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
