This is a bug report for perl from timbo@timac.local,
generated with the help of perlbug 1.39 running under perl 5.11.2.


-----------------------------------------------------------------
[Please describe your issue here]

Perl 5.8.6:
$ echo 1 > a.pl; perl -MData::Dumper -e 'BEGIN { $^P=0x2 } do "a.pl"; print Dumper(\@{"_<a.pl"})'
$VAR1 = [
          undef,
          '1
'
        ];

Perl 5.11.2:
$ echo 1 > a.pl; perl -MData::Dumper -e 'BEGIN { $^P=0x2 } do "a.pl"; print Dumper(\@{"_<a.pl"})'
$VAR1 = [
          '1
',
          ';',
          ';'
        ];

The primary problem is that source code line 1 used to be stored at index 1 but
is now stored at index 0. This breaks NYTProf tests and probably affects use of
the perl debugger.

A secondary problem is the extra semicolons that weren't in the original file.

A third problem is lack of tests for this in the test suite ;)
