7.2.57 sigtrap - Enable Stack Backtrace on Unexpected Signals

use sigtrap;       # initialize default signal handlers use sigtrap 

LIST

;  # 

LIST

 example:  qw(BUS SEGV PIPE SYS ABRT TRAP)

The sigtrap pragma initializes a signal handler for the signals specified in LIST , or (if no list is given) for a set of default signals. The signal handler prints a stack dump of the program and then issues a (non-trapped) ABRT signal.

In the absence of LIST , the signal handler is set up to deal with the ABRT , BUS , EMT , FPE , ILL , PIPE , QUIT , SEGV , SYS , TERM , and TRAP signals.
