ID: 41812 Updated by: tony2001@php.net Reported By: jan at horde dot org -Status: Open +Status: Feedback Bug Type: Documentation problem PHP Version: Irrelevant New Comment: Try this: gdb php b zif_var_dump r -r 'var_dump(1);' p (char*)(executor_globals.function_state_ptr->function)->common.function_name Previous Comments: ------------------------------------------------------------------------ [2007-06-27 09:02:36] jan at horde dot org I never, ever made a ZTS build of PHP in my whole life. And just to be sure, I verified with phpinfo(). Anything else I could check? I don't know my way through gdb, I only use it for generating backtraces. Is there a way to list the available symbols? ------------------------------------------------------------------------ [2007-06-27 08:45:55] tony2001@php.net Well, it looks like you did enable it, because it works perfectly fine here: Breakpoint 1, zif_var_dump (ht=1, return_value=0x836c1ac, return_value_ptr=0x0, this_ptr=0x0, return_value_used=0) at /local/dev/php/5_2/ext/standard/var.c:177 177 argc = ZEND_NUM_ARGS(); (gdb) print (char*)(executor_globals.function_state_ptr->function)->common.function_name $1 = 0x829c56b "var_dump" ------------------------------------------------------------------------ [2007-06-27 08:16:27] jan at horde dot org No, it's a debug non-zts linux build. ------------------------------------------------------------------------ [2007-06-26 12:47:01] tony2001@php.net Did you enable ZTS ? ------------------------------------------------------------------------ [2007-06-26 12:34:34] jan at horde dot org Description: ------------ The instructions to generate backtrace information on http://bugs.php.net/bugs-generating-backtrace.php don't work anymore with the latest PHP versions. print (char *)(executor_globals.function_state_ptr->function)->common.function_name results in: Address of symbol "executor_globals" is unknown. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41812&edit=1
