This is a bug report for perl from david@davidfavor.com,
generated with the help of perlbug 1.35 running under perl 5.9.5.


-----------------------------------------------------------------
[Please enter your report here]
Latest patch level today fixes realloc panic in CPAN module and
introduces a new panic when CPAN exits.

perl -MCPAN -e shell
CPAN: File::HomeDir loaded ok (v0.65)

cpan shell -- CPAN exploration and modules installation (v1.9102)
ReadLine support enabled

cpan[1]> quit
Lockfile removed.
panic: free from wrong pool during global destruction.

Probably best to add tests which reproduce the original realloc
from wrong pool problem and also reproduce this problem, since
test suite passes in both cases.
