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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=42509&edit=1
