Summary0000450: "Incomplete" backtraces when an exception gets rethrown
DescriptionTry the attached 'script'. I would have liked to know the exception was thrown in f6() however, unfortunately xdebug does show no more steps after f4(). This on itself is fairly well explainable, if it were not for php (without xdebug) to actually do show the exception was thrown in f6().

php version: 5.2.9, xdebug version 2.0.4
Additional Information<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
class test {
        function f4() {
                try {
                        $this->f5();
                } catch(exception $e) {
                        throw $e;
                }
        }

        function f5() {
                $this->f6();
        }

        function f6() {
                throw new exception('foo');
        }
}

$test = new test();

$test->f4();
?>

This is likely going to be difficult to fix.

Why would that be? The information *is* in the Exception, it can be shown from within PHP with `$e->getTrace()`. Xdebug cannot access it?

In fact, my long time workaround for this issue is:
```php
// Re-throw the exception
if (!extension_loaded('xdebug'))
  throw $e;
else
  throw new Exception(null, null, $e);
```
*Then* Xdebug does show the stack trace of the exception *in addition* to the (usually useless) stack trace of the re-throw.
