--- Comment #6 from Jeffrey A. Law <law at redhat dot com> ---
Well, given that gcse merely moves evaluations to other blocks where evaluation
of the expression is always anticipated, there's no inherent reason why we
can't gcse something that might trap.

It really feels like this is papering over the real problem, namely that
get_pressure_class_and_nregs simply doesn't handle things that are passed
through hash_scan_set, in particular cases where there's a single set inside a
PARALLEL.
