Description:
------------
default Exception handler and error_get_last() return error message with not full stack trace. When use large libraries like PHPSpreadsheet and got exception, message with stack trace contain only PHPSpreadsheet internal calls but where you call it is offcut.

Test script:
---------------
<?
	$limiter = 20;
	$func = function() use (&$limiter, &$func)
	{
		$limiter--;
		if (!$limiter)
		{
			print "<pre>";
			debug_print_backtrace();
			throw new Exception("test error");
		}

		if ($limiter <= 0)
			return;
		$func();
	};

	$func();
?>

Expected result:
----------------

there must be something else limiting the depth, because I cannot reproduce this. See https://3v4l.org/VhoFu - as you can see the exception backtrace is just as deep as the debug-backtrace is (unless this is Windows specific)

Can I get ini-file from 3v4l.org ?

try to increase $limiter to 50 on 3v4l.org. You will see the same problem.
