+; This testcase, obviously distilled from a large program (bzip2 from Specint2000)
+; caused instcombine to fail because it got the same instruction on it's worklist
+; more than once (which is ok), but then deleted the instruction. Since the inst
+; stayed on the worklist, as soon as it came back up to be processed, bad things
+; happened, and opt asserted.
+;
+; RUN: as < %s | opt -instcombine
