Bug #72359 [NoF->Csd]: Child exited with status 4294967295

Edit report at https://bugs.php.net/bug.php?id=72359&edit=1 ID: 72359 User updated by: oldbucsfan at hotmail dot com Reported by: oldbucsfan at hotmail dot com Summary: Child exited with status 4294967295 -Status: No Feedback +Status: Closed Type: Bug Package: Apache2 related Operating System: Windows Server 2012 R2 PHP Version: 7.0.7 Block user comment: N Private report: N New Comment: Still occurring with 7.0.14. Using abs.exe in apache and simply hitting the wordpress index.php page 1000 times will often lead to one of these errors. Calling stream_get_wrappers() does not trigger it, but I haven't tried calling it 1000s of times. It does seem to be connected to that function though.

The bug is being suspended because we assume that you are no longer experiencing the problem.

Thank you. ------------------------------------------------------------------------ [2016-08-07 04:08:52] kalle@php.net Interesting, the last two backtraces hint that something is related to stream_get_wrappers(), in particular when populating the return array, which seems to be called from a callback in a method. Does a regular call to stream_get_wrappers() crash PHP? ------------------------------------------------------------------------ [2016-06-21 20:46:48] oldbucsfan at hotmail dot com Found this in the Wordpress debug log. PHP Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method allow_php_in_posts::shortcode_advanced() should not be called statically in C:\Apache24\htdocs\wordpress\wp-includes\plugin.php on line 235 I think this might explain it. Should this lead to a memory leak and crash Apache though? Anyway, I removed the plugin and things are more stable, but I will have to give it more time to know if it solved the problem. ------------------------------------------------------------------------ [2016-06-17 14:08:15] oldbucsfan at hotmail dot com Ran another catch. It seems that increasing the threads per child makes this happen less often for some reason. Anyway, I ran the catch to analyze memory and got more info. Seems to have to do with make_sha1_digest in php5ts.dll PHP7TS!MAKE_SHA1_DIGEST+3AD4WARNING - DebugDiag was not able to locate debug symbols for \php7ts.dll, so the information below may be incomplete.
