From: thomas dot hebinck at digionline dot de Operating system: Linux PHP version: 5.2.4 PHP Bug Type: *Math Functions Bug description: GMP without gmp_init eats memory
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 -- Edit bug report at http://bugs.php.net/?id=42509&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42509&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42509&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42509&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42509&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42509&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42509&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42509&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42509&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42509&r=support Expected behavior: http://bugs.php.net/fix.php?id=42509&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42509&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42509&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42509&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42509&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42509&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42509&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42509&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42509&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42509&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42509&r=mysqlcfg
