So i found a problem with ctype_digit() function, who seems to crash PHP with a big (or not ?) integer. Reproduce code: --------------- <? $id = 1000000000; ctype_digit($id); ?> Expected result: ---------------- A warning or something like that, because $id is an integer, but not a segfault... Actual result: -------------- nothing, except a new line in my apache error_log file : [Thu Aug 26 00:00:18 2004] [notice] child pid 3877 exit signal Segmentation fault (11) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29843&edit=1
