[ID 20000325.009] `syntax error' message not trapped by $SIG{__DIE__}
Message ID:
20000326062608.22868.qmail@plover.com
This is a bug report for perl from mjd@plover.com,
generated with the help of perlbug 1.26 running under perl 5.00503.


-----------------------------------------------------------------
[Please enter your report here]

Here's a sample program:

        #!/usr/bin/perl


        sub foo { 
          print "TRAPPED MESSAGE $_[0]\n";
          exit 0;
        }

        BEGIN { $SIG{__DIE__} = \&foo }

        1+(2*3;


When run with 5.005_03 or 5.6.0, this yields:


        syntax error at test.pl line 5, near "3;"
        TRAPPED MESSAGE Execution of test.pl aborted due to compilation errors.

I want the `syntax error' message to be trapped also.  The discussion
of $SIG{__DIE__} in `perlvar' suggests that it should be trapped:

               `__DIE__'/`__WARN__' handlers are very special in
               one respect: they may be called to report (proba-
               ble) errors found by the parser.  In such a case
               the parser may be in inconsistent state
