There is dead code reported in this issue and I think no need to check for NULL of 'handler' in function faulthandler_fatal_error() and file Python-3.4.3/Modules/faulthandler.c . where 'handler' is pointed to staic array faulthandler_handlers[] which never will be null inside loop with faulthandler_nsignals value and doesn't means to check for NULL outside of loop. but if there is possibility of 'handler' to be NULL then it should be check inside the loop until
handler->signum is not equal to signum and then break;

The check is required to fix a compiler warning. Please keep it, it doesn't

Maybe add a comment to explain it.
