This is a bug report for perl from perlbug@plan9.de,
generated with the help of perlbug 1.39 running under perl 5.12.4.


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

Carp::shortmess/longmess leak memory, and as a result all functions in the
Carp module. It doesn'T seem to be hard to trigger:

   perl -e 'use Carp; Carp::shortmess while 1'

This leaks about 12mb/s on my system. When using longmess and a longer
backtrace is generated, it leaks faster.
