This is a bug report for perl from vlyon@cpan.org,generated with the help of perlbug 1.39 running under perl 5.10.1.

-----------------------------------------------------------------
Storable croaks when trying to freeze a blessed REF object for a class that contains a STORABLE_freeze hook.
my $obj = bless \[], "Abc";Storable::freeze($obj);
No problems with the code above until you add:
package Abc;sub STORABLE_freeze {}
Then it croaks with:
Unexpected object type (0) in store_hook() at ...
This is because store_hook() in Storable.xs only deals with svis_SCALAR, svis_ARRAY, svis_HASH & svis_TIED.It needs to also deal with svis_REF.My guess is that tied REFs wont work either, but I haven't tested this.
