Unfortunately, this affects all regex compiles, not just empty ones
(that was just a short example to test to see if your version has the
problem). So, if you have any qr// operators in loops or you say
something like
my $foo = "test";
while (<>) {
/$foo/;
}
Each compile of a regex will leak a little more memory. For the most
part programs will not be adversely affected by this leak (due to the
generally small number of regexes compiled), but daemons that compile
regexes on the fly will slowly consume more and more memory.
