Previous Comments: ------------------------------------------------------------------------ [2005-11-21 08:52:09] shulmanb at il dot ibm dot com Thanks for including the fix. From what I've seen, it has been included in HEAD, and in 5.1.x. Any chance of it being included in 5.0.x as well? ------------------------------------------------------------------------ [2005-11-20 19:08:11] sniper@php.net This bug has been fixed in CVS.

Can be found at: http://news.php.net/php.internals/20164 ------------------------------------------------------------------------ [2005-11-16 18:18:33] sniper@php.net And if it's still a problem, provide the patch in unified diff format. ------------------------------------------------------------------------ [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
