[g-arc-opts] When creating increments, decrements do not use the SILLocation of the insertion point. If the insertion point is a terminator instruction, the increment, decrement will get a SILLocation that is not valid on non-terminator instructions which will cause an assertion to be hit.

I am going to speak with Adrian in the coming week about what is the
correct thing to do here.
