This is a bug report for perl from arc@cpan.org,
generated with the help of perlbug 1.39 running under perl 5.13.5.


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

As of bf236c8ee5b1b47df84e2e196fb90a43c6abd5a2, lib/Carp.pm contains a bare
reference to \&CORE::GLOBAL::caller.  This autovivifies
$CORE::GLOBAL::{caller}, which could be annoying in some situations.

The attached patch fixes that, and adds a test to prevent it happening again.

[Please do not change anything below this line]
