Your code makes no sense:

  $retVal = $someObject->bar()->doSomething();
  $retVal = \$retVal;

You overwrite $retVal immediately. Maybe you meant:

  my $myVal = $someObject->bar()->doSomething();
  $retVal = \$myVal;
  Log4perl->debug('retval: ', sub {$retVal});
  return $retVal;

Then, I think you won't have a memory leak, as the only thing that's keeping $myVal alive is the reference in $retVal. When that reference goes out of scope, also $myVal will get released.
