#35243 [Opn->Fbk]: Crashes in php_mblen when compiled with thread-safety on Linux

ID: 35243 Updated by: sniper@php.net Reported By: shulmanb at il dot ibm dot com -Status: Open +Status: Feedback Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 5.0.5 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip Previous Comments: ------------------------------------------------------------------------ [2005-11-16 16:07:01] shulmanb at il dot ibm dot com Description: ------------ When running on Linux with --enable-maintainer-zts (and yes, I know it's not wise...), crashes sometimes happen in ext/standard/php_string.h when using the php_mblen macro. This happens because in ext/standard/basic_functions.c, in the basic_globals_ctor function, the value of mblen_state is not initialized. The basic_globals_ctor function should include the following lines as part of the initialization: #if defined(_REENTRANT)&&defined(HAVE_MBRLEN)&&defined(HAVE_MBSTATE_T) memset(&BG(mblen_state), 0, sizeof(BG(mblen_state))); #endif Unfortunately, I am unable to include code that demonstrate this, as the crash strongly depends on the (random) value of mblen_state. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35243&edit=1
