I'm actually going to close this. The issue seems to have disappeared. I did review some of the changes that went in and I'm not sure which one is responsible for fixing it. But I can build the current HEAD on both a RISC-V vm and my VisionFive 2 board with GCC 12.3 and with no failures.

If it re-occurs, the fix suggested by @stefank is probably the best trade-off.
