evaluate_prg_hwy.ii.xz

Originally reported downstream in Gentoo at https://bugs.gentoo.org/905818.

With GCC 12 (12.2.1 20230505), this has reached over 30GB memory usage befo=
re I
killed it. I've asked the reporter for preprocessed source for 13 as well.

Reproduces for me with 12 using:
```
g++-12 -c evaluate_prg_hwy.ii -std=3Dc++20 -O2
```
but even -O0 is enough.=
