This seems to work when calling bash again. Otherwise,
we can get something like:

This is half a liEXIT=123
diff --git a/regression/test.pl b/regression/test.pl

-  print $FH "SIGNAL=$signal_num\n";
-  close $FH;
+  system("bash", "-c", "cd '$name' ; echo '\nEXIT=$exit_value\nSIGNAL=$signal_num\n' >> '$output'");
 
   if($signal_num == 2) {
     print "\nProgram under test interrupted; stopping\n";
