Try to compile the given code. dmd crashes with a segmentation fault. It shouldn't crash, but show an error message.

There's a cycle when trying to solve T. Somewhere the ".inuse" member of the declaration of function "f" must be incremented and later decremented to detect the cycle.
Just gotta find the right place, using the backtrace of the ICE, because this case is tricky. You can fix it at several place but then it breaks the test suite or even some stuff in druntime.
