Description:
------------
PHP crashes if a __call()- and __callStatic()-method exists, whereas __call() redirects calls to __callStatic(), this is likely related to http://bugs.php.net/bug.php?id=49542

System:
Microsoft IIS 7.5
PHP 5.3.6 NTS

Test script:
---------------
Foo-Class (crashes): http://nopaste.php-quake.net/27860
Bar-Class (work-around): http://nopaste.php-quake.net/27861

Expected result:
----------------
// Foo-Class
Called static method one()
Called static method three()

// Bar-Class
Called static method one()
Called static method three()

Actual result:
--------------
// Foo-Class
PHP-Crash

// Bar-Class
Called static method one()
Called static method three()

The crash is caused by call stack overflow due Foo::three() be called with object context, so __call() is called instead of __callStatic().
You just need to make the method 'two' static, so __callStatic() will be called.

Maybe my example wasn't sufficient enough to show the problem, imagine the following code [1] which causes a crash too. I would expect some kind of error handling, instead of PHP just going down.

Once again this is related to PHPs "feature" to allow static calls from non-static context and vise versa but this should not cause a crash anyway.
