Both of the unions in the test case can be replaced with structs without
changing the behaviour.
The union inside circular_definition must be anonymous. If it is given a name, 
compilation succeeds.
Also, if  union any {} is changed into: alias int any; then it segfaults on
2.038.
So the fact that it started segfaulting on the union case is probably not
important.
