Summary0000450: "Incomplete" backtraces when an exception gets rethrown
Description

Try 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.

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:

// 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.

Thanks for fixing!

I'll have to admit I had totally forgotten this 14 year old issue, but it's great to see that even though it's been sitting idle for a while it was still picked up. Thanks & have a good one!

ps I have no idea why I used f4,f5 and f6, instead of e.g. f1-3. Guess we'll never know...
