I'm continuing to look into the best way to avoid the compiler crash. I want
to note that this code is being clobbered by undefined signed overflow.
Computing (19780211 + [-128,127]) * 43321879 is always going to overflow, so
VRP is converting that into hash = INT_MAX. That is almost certainly not what
is intended. This is independent of my -Wstrict-overflow work, although my
-Wstrict-overflow work is indeed causing the compiler crash.
