testcase (C source)

File this one under "crazy situations created by the mono test suite".

If you create a window, change its parent to itself (using SetWindowLong[Ptr]
with GWL[P]_HWNDPARENT), and then destroy the window, DestroyWindow recurses
infinitely and causes a stack overflow.

Test case attached.
