-; Make sure we don't crash on this example. This test is supposed to test that
-; MergeFunctions clears its GlobalNumbers value map. If this map still contains
-; entries when running globalopt and the MergeFunctions instance is still alive
-; the optimization of @G would cause an assert because globalopt would do an
-; RAUW on @G which still exists as an entry in the GlobalNumbers ValueMap which
-; causes an assert in the ValueHandle call back because we are RAUWing with a
-; different type (AllocaInst) than its key type (GlobalValue).
