[Vala] Incorrect enum / switch usage causing segfault in 0.9.4 (and previous)

[Dru Moore <dru dru-id co uk>]

This came up because of a stupid error in my code but, incorrect (i.e.
stupid!) use of an enum in a switch statement is segfaulting the code
generator on both 64bit x86 and armel platforms on Linux. As I say
it's clearly stupid on the part of the programmer but it should not
compile rather than segfault I guess.

Below is the smallest example I could devise that exhibits the
segfault in 0.9.4, but the behaviour is consistent as complexity
grows.

I've filed it as bug https://bugzilla.gnome.org/show_bug.cgi?id=626397
but will remove it if deemed inappropriate.

public static int main(string[] args) {
  Test test = {TheEnumerator.ONE};
  switch (TheEnumerator) { // clearly should be test.the_enumerator !
    case TheEnumerator.ONE:
      break;
    default:
      break;
  }
  return 0;
}

public enum TheEnumerator {
  ONE
}

public struct Test {
  TheEnumerator the_enumerator;
}
