Hi,

fixed: https://gist.github.com/bukka/9936176 [3]

The main problem was that you are trying to save return_value to static variable and then re-use it ( https://github.com/kdolinar/hypx-zend-bugcase/blob/master/src/hypx.c#L302 [4] )

That won't work because of GC (value can be freed in the meantime). There were also some memory leaks and missing TSRMLS that I fixed. Compare the the gist file and you will see that. I fixed just this case so the index.php works. However there might be more similar case that you need to check...

Thanks, Jakub, very much for your insight. Yes, obviously saving a return_value into a static property was a bad idea. But how can I then create a persistent object and assign it to a static property? Here I'm after a typical singleton class where the only instance of the object is kept in a private static property.
