           Summary: nested overloaded foreach in contract crashes dmd
           Product: D

            Status: NEW
          Severity: normal
          Priority: P2

The following code crashes DMD v2.053 with "Internal error: ../ztc/cgcs.c 363":


class foo {
  int opApply(int delegate(ref int) dg) const { return 0; }

  foo bar()
    out(result) {
      foreach (x ; result)
        foreach (y ; result)
          assert(x);
    }
  body { return this; }
}


I haven't been able to simplify the code any further and still reproduce the
crash.  Removing the second foreach makes it compile, as does replacing
"assert(x)" with anything not referring to "x".
