I've frequently run into the following problem. I've searched Perlmonks, and seen a few similar situations , but I didn't see a clear answer. It sounds like it is a bug in Perl? When passing an array as a reference to a subroutine, like this: 
subroutine(\@list)

and using it internal to the subroutine, like this: 
$count=$#(@$listref);

I get the folling error message, only in debug mode: 
"Bizarre copy of ARRAY in leave at..."

[download]
The code works fine, and does the right thing, it just fails in debug mode. The inelegant work-around is to do an intermediate step: 
my @local_array=@$list;
my $count=$#local_array;

[download]
Any ideas on this problem?
