Description:
------------
Various GMP Functions eat memory, when not called directly with
integers or strings instead of gmp resources.
Reproduce code:
---------------
$a='1234';
for($i=0;$i<200000;$i++) {
$c=gmp_add(gmp_init($a),gmp_init($a));
}
echo memory_get_usage() . "¶\n";
for($i=0;$i<200000;$i++) {
$c=gmp_add($a,$a);
}
echo memory_get_usage() . "¶\n";
Expected result:
----------------
Both memory_get_usage() should show nearly the same values.
Actual result:
--------------
1732656¶ // ~ 2 MB
43809696¶ // ~ 43 MB
