Disable backtrack bug
Description:
------------
In all cases (but the one below one), "file" and "line" indexes are defined in each frame of the output of debug_backtrace.
But when using call_user_function() or call_user_function_array, "file" and "line" is not defined for one of the frames.
It would be nice if I could count on file and line always being defined when using the output of debug_backtrace, thereby avoiding code for special cases.
For the missing file and line in the example code below, when calling f() inside call_user_function(), I suggest using the file and line of the call_user_function() call.
See also bug 38047 and 24405.
Reproduce code:
---------------
<?php
error_reporting(E_ALL | E_STRICT);
function f() {
$a = $b;
var_dump(debug_backtrace());
}
//The backtrace generated here will not have file and line defined
call_user_func("f", Array());
//The backtrace generated here will have file and line defined.
f();
?>
Expected result:
----------------
The frame with index 0 of the first debug_backtrace_call should contain indexes "file" => "test.php" and "line" => 6
Actual result:
--------------
