Hi,

As first reported by PerlMonks user Eily at 
http://www.perlmonks.org/?node_id=11102239 :

The output of the attached script under Linux, Perls 5.20.0 through 
5.30.0, is as expected:
--8<--
Regex!
Item: Bar
Item: Foo
Regex!
-->8--

However, under Strawberry Perl 5.30.0.1-64bit on Win 7, the output is:
--8<--
Regex!

Item: Bar

Item: Foo

Use of uninitialized value in say at strangebug.pl line 4.

Foo

-->8--

This seems to be some really strange memory (stack? dunno) issue that I 
can't further diagnose myself. I also haven't been able to make the 
example code much shorter yet.

Regards,
