This is a bug report for perl from hsr@cs.stanford.edu,
generated with the help of perlbug 1.34 running under perl v5.8.0.
-----------------------------------------------------------------
Perl crashes on the following test program:
use threads;
use threads::shared;
my %hash : shared;
exists $hash{1};
The error message is: 'Free to wrong pool 15d26e8 not 1aeb8f0.'
The bug disappears if I eliminate the 'shared' keyword, or if I
use an array instead of a hash.
