The following test program gives this error:
Bizarre copy of ARRAY in sassign at /usr/lib/perl5/5.8.8/Carp/Heavy.pm line 45.
Tested on the 5.8.x branch and on perl-current.
use Carp;
sub do_carp {
print Carp::longmess;
}
sub call_with_args {
my ($arg_hash, $func) = @_;
$func->(@{$arg_hash->{'args'}});
}
my $h = {};
# Deleting the undef makes it all work again!
my $arg_hash = {'args' => [undef]};
call_with_args($arg_hash, sub {
$arg_hash->{'args'} = [];
do_carp(sub { $h; });
});
