Bug description:Memory leak in gmp_cmp second parameter
Description:
Reporting this bug for a third party
(http://www.reddit.com/r/PHP/comments/1hx7qz/what_is_going_on_here_how_do_i_fix_t
his_memory/), and related to a user note
(http://www.php.net/manual/en/function.gmp-cmp.php#99120).
The gmp_cmp function leaks memory when a string is used as the value of the
second parameter.
My guess is that it relates to the way that the type is juggled in the
gmp_cmp
function (https://github.com/php/php-src/blob/master/ext/gmp/gmp.c#L848),
where
it checks the type of the second parameter to see if it's a long. It
doesn't
however check if the second parameter is a string, or really any other
type.
