Just a note, it only crashes when optimization flag is set.

-O0 works fine
-O1 crashes
-O2 crashes
-O3 crashes

We don't support any magic methods at the moment.

Actually, I'm surprised this works in the -O0 case.

I also tested with a simple class, like this:

class x
{
   private $y;
}

$z = new x();

It also segfaults when using -O3

I think we don't support variable modifiers ('private'). It should work without that.
