In (A), the segfault is happening in SwitchStatement::semantic(Scope*)
[statement.c:3101], from attempting to dereference a null pointer (body =
body->semantic(sc); where body==NULL). Looks like the body is null because it
was an invalid switch mixin, but for some reason the compiler didn't catch the
syntax error and proceeded to create a SwitchStatement with a NULL body.
