From @schwern

My co-worker ran into this problem. It appears that a compiled regex
used inside a /x pattern needs to be /x as well. The following

$pat = 'foo';
$c_pat = qr/foo/;
$c_pat_fixed = qr/foo/x;

$string = 'foo';

$\ = $/;
print 'normal​: ', $string =~ / $pat /x ? 'Yes' : 'No';
print 'qr​: ', $string =~ / $c_pat /x ? 'Yes' : 'No';
print 'fixed qr​: ', $string =~ / $c_pat_fixed /x ? 'Yes' : 'No';

I've noted this failure under 5.005_03/Linux and 5.005_02/Linux
