Test script: --------------- <?php function errorHandler($level, $msg){ $debug = debug_backtrace(); $debug[1]['args'][0]='1'; return true; } set_error_handler('error'); function a($a){ // E_RECOVERABLE_ERROR var_dump($a); } class A{} a(1); a(2); a(new A()); ?> Expected result: ---------------- int 1 int 1 int 1 Actual result: -------------- int 1 int 1 object A ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53731&edit=1
