Is there any way to catch E_PARSE? As you can see ob_* is dead end ;) ------------------------------------------------------------------------ [2012-03-28 16:42:41] reeze dot xia at gmail dot com @grzegorz129 maybe the title can be more specific: eg: Segfault using ob_clean/flush* functions in output_callback function ------------------------------------------------------------------------ [2012-03-28 16:40:46] reeze dot xia at gmail dot com I've sent a pull request to fix this. @see https://github.com/php/php-src/pull/25 this makes php raise fatal error instead of segfault. This seems to be a logic error when clean/flush output will cause the callback called and then endless function call. ------------------------------------------------------------------------ [2012-03-28 15:09:36] grzegorz129 at gmail dot com Test script can be even simplier: <?php ob_start('foo'); function foo() { ob_end_clean(); } ?> ------------------------------------------------------------------------ [2012-03-28 14:51:09] sixd@php.net Changed summary from "Memory leak during using ob_*" ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
