I'm not completely sure about this: the original code was
fine at -O2 on x86_64 and failed at -O3 on the same machine.

#38564 did not use -O3, but did use only -O2.

Given that tree-ssa-pre.c:3131 is some sort of assert,
I speculate that this bug report is causing an assert
fail in the same place, but perhaps for a slightly different reason.

Indeed, there may even be a case for splitting up the assert
expression to make more clear what's failing.

Guidance sought.
