Reproduce code: --------------- <? include('Smarty.class.php'); $smarty = new Smarty(); $smarty->debugging = true; // the error will not occur if debugging = false set_error_handler("error_handler",E_ALL); function error_handler($errno, $errstr, $errfile, $errline, $errcontext) { global $smarty; $smarty->assign('killme',$errcontext); $smarty->display('killsmarty.tpl'); // this file can be empty but it has to exist echo($errstr); } trigger_error("Uh-ho!",E_USER_ERROR); ?> Expected result: ---------------- $errcontext should be assigned to Smarty template variable $killme. Actual result: -------------- #0 0xb7a56e40 in vfprintf () from /lib/tls/libc.so.6 #1 0xb7a73ffb in vsprintf () from /lib/tls/libc.so.6 #2 0xb7a5fe1e in sprintf () from /lib/tls/libc.so.6 #3 0x08277eb1 in _convert_to_string () #4 0x0827f684 in zend_make_printable_zval () #5 0x08277a1c in concat_function () #6 0x082a2b7e in execute () #7 0x0829d9c8 in execute () #8 0x0829bf83 in zend_get_user_opcode_handler () #9 0x00000000 in ??
