(Given example there: if (empty($var)) { echo '$var is either 0, empty, or not set at all'; }) However, when $var really is not set, i get a Memory Leak (in a big script). I reduced the script to the code below and now even get a Segmentation fault. Reproduce code: --------------- <?php if(empty($foo)){ echo 'empty'; }else{ echo 'not empty'; } ?> Expected result: ---------------- Echoing "empty" and nothing else. Actual result: -------------- Echoing "empty" Valgrind says: http://tdc.medieval-wars.de/valgrind.txt.pid27963 Probably most important: ==27963== Process terminating with default action of signal 11 (SIGSEGV) ==27963== Access not within mapped region at address 0xF45 ==27963== at 0x81EDD17: zend_execute_scripts (/home/necmon/php5-200501101930/Zend/zend.c:1059) ==27963== by 0x819E50D: php_execute_script (/home/necmon/php5-200501101930/main/main.c:1636) ==27963== by 0x8277DAE: main (/home/necmon/php5-200501101930/sapi/cli/php_cli.c:944) (Note: this does NOT only happen with the cli version!) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31478&edit=1
