Reproduce code: --------------- // Not relevant to the bug $file = tempnam('./', ''); file_put_contents($file, ' foo =1; foo[]=1; '); // Will make PHP crash parse_ini_file($file); Expected result: ---------------- In the attached reproduce code we create a ini file which has 2 keys, "foo" and "foo[]" then we execute parse_ini_file() on the newly-created file. Because "Characters {}|&~![()" must not be used anywhere in the key" (dixit the manual) I'd expect an error message, or at least a Strict notice. Actual result: -------------- PHP segfaults/crashes (tested on 5.2.1 on WinXP and 5.1.2 on Ubuntu 6.06) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40752&edit=1
