You can check all the failure possibilities by inspecting $? like this:

                   if ($? == -1) {
                       print "failed to execute: $!\n";
                   }
                   elsif ($? & 127) {
                       printf "child died with signal %d, %s coredump\
+n",
                           ($? & 127),  ($? & 128) ? 'with' : 'without
+';
                   }
                   else {
                       printf "child exited with value %d\n", $? >> 8;
                   }
