Any gmp_* function running on PHP 5.2.2-r1 (compiled with GMP extensions), throws after a few invokes "Fatal error: Allowed memory size of <varies from 7M to 8M> bytes exhausted (tried to allocate 16 bytes) in <file.php>". The CLI program <file.php> works fine with PHP 5.1.6-r11; hardware hasn't been updated (so RAM is up to 2GB). Reproducible: Always Steps to Reproduce: 1. emerge php-5.2.2-r1 2. run an iterated procedure which works with gmp functions (such as gmp_init, gmp_div, gmp_and, etc.), like this: for( $i= 0; $i!= 100000; $i++ ) { $node = gmp_init( $i ); $id = gmp_div( $node, '0x100000000' ); $edge = gmp_and( $node, '0xffffffff' ); $vert = gmp_div( $node, '0x1000' ); $path = gmp_and( $node, '0x00ff' ); $str_edge = gmp_strval( $edge ); $str_vert = gmp_strval( $vert ); $str_path = gmp_strval( $path ); echo "Graph -> ($str_edge, $str_vert, $str_path) \n"; } Actual Results: Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 16 bytes) in quixtor/compute-graph-map.php on line 443. (actually line 443 isn't a gmp related function, but it is called under for() iteration which uses GMP functions) Expected Results: The iterated procedure runs on PHP 5.1.x (and PHP 5.0.x) near to 1 million times per call. In this case, it's only runs 500 times and then drop the Fatal error.
This is still reproducible using the latest CVS snapshot (php-5.2.4_pre200708051230-r2). Please, report this upstream (http://bugs.php.net/) and post the URL here for tracking; we don't apply any gmp-related patches, not a Gentoo issue most likely.
