[BUG 5.005_03] Data::Dumper underrefs

crypt% perl -MData::Dumper -we '$self = bless {}; $self->{a} = []; $self->{a}[1] = 0; $self->{b} = $self; Dumper($self)'
Attempt to free unreferenced scalar during global destruction.
crypt% 

Cannot reproduce with _61 but I'm not sure whether the bug has been fixed
in perl or in Data::Dumper, so I thought it was worth a mention.
