The testcase was looking for two conditional assignments, both based on the same predicate register, but with one condition "if-true" and the other "if-false".  The original bug was that the "kill" flag on the condition register wasn't cleared on the first assignment and so it was killed before the second conditional assignment (causing a verifier error).  I just replaced this testcase with a .mir version, so it's no longer there.
