This is a bug report for perl from perl@galumph.com,
generated with the help of perlbug 1.39 running under perl 5.12.2.


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

STDERR isn't being unlocalized when there's an unhandled exception.  For
example,

     perl -E 'open my $h, ">", \$string; local *STDERR = $h; die "blah"'

doesn't emit anything.  That's global scope you say?  The following shows the
same problem:

     sub foo {
         die q<why doesn't this show up?>;
     }

     sub bar {
         my $x;
         open my $h, '>', \$x;
         local *STDERR = $h;
         foo();
     }

     bar();

I expect STDERR to be delocalized before final exeption handling kicks in.
It's as if the lexical scope isn't being left.
