Created an attachment (id=1304)
Sample program that reproduces the desribed error.

When an in-contract of an interface fails, the in-contract of the implementing
class is used. This works fine in single-threaded applications. In
multithreaded applications however, the program freezes after a while when
executing the in-contract of the interface. I attached a small program "main.d"
that shows the problem. The program should execute endlessly, but in fact it
freezes always at the same spot. The output is always:

...
foo 401
base in-contract
derived in-contract
foo 402
base in-contract
derived in-contract
foo 403
base in-contract
[freezes]

Using my debugger I found out, that the Garbage Collector always freezes in
multithreading. GC.collect() causes an instant freeze when more than one thread
is running.

Seems to be fixed in the most recent version in the repository.
