Fail was due to a bug in IAI whose reset() method was not clearing the set holding pointers to the interleave groups being deleted, uncovered by this patch's use of the set. Patch recommited as 100e797adb433724a17c9b42b6533cd634cb796b <https://reviews.llvm.org/rG100e797adb433724a17c9b42b6533cd634cb796b> with a fix to reset().
Thanks Benjamin!
