This happens in PHP-5.0.0 PHP-5.0.1 PHP-5.0.2 PHP-5.1 HEAD The cause happened to be zend_do_begin_method_call in zend_compile.c. Here the check exists to check the member method name is __clone. This check causes a Segmentation fault. Solution is check for the, last_op->op2.u.constant.type==IS_STRING before chceking for str.len and zend_binary_strcasecmp. This bug breaks the working of Xoops 2.0.8 PHP5.0 port of Xoops. Reproduce code: --------------- Segmentation fault case <?php $obj->kameaps[0](); ?> Non Segmentation fault case <?php $obj->anymembernamenotequalto7insize[0](); ?> Expected result: ---------------- Fatal error: Function name must be a string in %s on line %d Actual result: -------------- Segmentation fault. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30457&edit=1
