I'm having trouble upgrading a system running 9-stable to a new

Since the tinderboxes for stable/9 are green, it is most likely your
machine has a hardware problem. You should at least run two or three
full passes of memtest on your machine: this type of error typically
occurs when data in RAM gets corrupted.
The box has ECC RAM, and runs pure zfs.
I don't know what to look out for regarding ECC errors though. There's
nothing in the console log that looks suspicious.
Also, trying to compile this many times will always trigger the same
error, that'd make RAM fault unlikely I would have thought (think random
crashes, the box is rock solid otherwise).
If you can't find any hardware problems, you could try to switch off
building clang, using WITHOUT_CLANG in your src.conf.
Thanks, will try that!
