This is with the host compiler so this might not be something which we could
help with.

well, I mean, it *ought* to be possible to bootstrap with GCC 11 as the host
compiler, right? The "transition to C++14" thread on the mailing lists was just
talking about raising the requirement for the host compiler to GCC 5, which is
still significantly older than GCC 11...

The problem is that it's riscv (so 11 is prehistoric in that context) and it's
also a huge generated file.

tbh, I suspect if you re-run the failing command, it might even succeed. The
riscv boards often aren't very stable..

The difference is "code we might massage to make it compile" vs "no idea why
the host compiler is ICEing", i.e. language support vs bugginess.

Hm, indeed, I'm trying it without the `-j2` this time, and it seems to be
getting past that spot... maybe it was hitting some sort of resource limit due
to the parallelism?

If I had to bet, it's overheating.

For any "segmentation fault" it's better to rule out hardware issues before
making a bug report.

The Unmatched has a temperature sensor that can be watched with sensors.
