Thanks for answering.
I can run it fine by disable zend_extensions.
Is it possible to run the code with zend_extensions?

Works perfectly fine here.
Please make sure all zend_extensions (like Zend Optimizer, APC,
eAccelerator etc.) are disabled.

return debug_backtrace();
}
function display($dummy,$bk){
print_r($bk);

function display2($bk){
print_r($bk);
}
function callMethod($methodname){
$ret = call_user_func(array($this,$methodname));
return $ret;
}
function execute(){
//CRASH!
$this->display("dummy",$this->backtrace());
//this works fine
// $this->display("dummy",debug_backtrace());
//this works fine too (only one arg)
