This is a bug report for perl from jm@jmason.org,
generated with the help of perlbug 1.36 running under perl 5.10.0.


-----------------------------------------------------------------
Easiest to demo this bug:


: 448...; cat Testcase.pm 
package Testcase;
use warnings;
use strict;
use Testcase;
sub foo { };

#foo "bar";     # is fine, exits 0
foo "bar");     # compilation fails with 'Unknown error'

glob "irrelevant";
1;

: 449...; perl -I. Testcase.pm 
Unknown error
Compilation failed in require at Testcase.pm line 4.
BEGIN failed--compilation aborted at Testcase.pm line 4.


If I switch the commenting on the "foo" lines, I instead see:

Subroutine foo redefined at Testcase.pm line 6.

which is what you'd expect.  If I comment the "glob" line I see:

syntax error at Testcase.pm line 9, near ""bar")"
Compilation failed in require at Testcase.pm line 4.
BEGIN failed--compilation aborted at Testcase.pm line 4.

Which again is what you'd expect.

This may be related to:
http://rt.perl.org/rt3//Public/Bug/Display.html?id=49472
Just thought I'd report it seeing as 5.10.0 is the current
default perl for Ubuntu...

cheers,

--j.
