I know about Devel::LeakTrace::Fast, but it requires a perl built for debugging, doesn't it?
Test::LeakTrace seems to do what you need, and it does not require a debug build:
my @info = leaked_info
my @array = ();
$ref = \@array;
# undef $ref;
print join(', ', @$_) for @info;
Output (leaked SV, filename, line number):
ARRAY(0x1ddd33c), 99_SoPW.pl, 10
But, with undef $ref; uncommented, it gives no output (as there is then no leak).
