good catch! I actually had added in the verify options later, because might as well enable that for tests. The failure that was used for test case reduction was elsewhere, because unequal vector lengths passed to allocTypesMatch. Fixing this typo actually caused the test to start failing, because I forgot to also pipe stderr through FileCheck, which I also fixed.
