Bug description: Crash instantiating classes with self-referencing constants
Description:
------------
When instantiating classes with self-referencing constants PHP crashes.
It is reproducable on Windows (5.2.3), Mac (5.2.2) and Linux (5.2.0).
Reproduce code:
---------------
class b {
const FOO = self::FOO;
}
new b();
echo "1";
Expected result:
----------------
1
Actual result:
--------------
No output, segmentation fault instead. Since I don't have MSVC available
for backtrace, I tried on a mac and linux box, same result (but Versions
were 5.2.2 and 5.2.0).
Looks like an endless recursion.
