The same bug can be triggered with

 % perl -Mencoding=utf8 -e 'map { "a" . $a } ((1)x500);'
 Attempt to free non-existent shared string 'original', Perl interpreter: 0x80f010 during global destruction.
 zsh: segmentation fault (core dumped)  perl -Mencoding=utf8 -e 'map { "a" . $a } ((1)x500);'

I've reported this upstream with the attached proposed patch. See the upstream
report for more details.

It should be easy to backport the patch to 5.10.1. Will try to get that
in squeeze.
