PHP Bug Type: Unknown/Other Function
Bug description: debug_backtrace doesn't reference arguments in stack in some
cases
Description:
------------
When argument of function or method is defined with type declaration and
default value and is called with some value of this argument,
debug_backtrace() doesn't reference this argument of function in stack.
When function definition is the same except argument doesn't have
default value, everything goes normal.
Reproduce code:
---------------
<?php function error($message,$number){
$traces=debug_backtrace();
$traces[1]['args'][0]='1';
return TRUE;
}
set_error_handler('error');
function a(anyUndefinedType $a){ // E_RECOVERABLE_ERROR
var_dump($a===1,$a==='1');
}
function b(anyUndefinedType $b=NULL){ // E_RECOVERABLE_ERROR
var_dump($b===1,$b==='1');
}
a(1);
b(1); ?>
Expected result:
----------------
bool(false) bool(true)
bool(false) bool(true)
Actual result:
--------------
bool(false) bool(true)
bool(true) bool(false)
