Ack, I had a thinko with

unsigned steps[] = {1, 1};

because in that case too n_steps doesn't get decremented, resulting in OOB
access.  I'm going to look at the original report[1] to see if the test case
reduction was valid and will close this out as invalid if there's nothing
interesting for the compiler to do there.  Thanks!
