Hi Eli,
Thanks for replying, the error happened when I compiled the master
branch (a7400cb8810) on Ubuntu 20.04, clang-20, libgccjit-14.

I spent more than 1 hours to search what caused the issue on my local
but didn't find the root cause, clean up and rebuild didn't help, so I
posted the error messages to mail list for searching helping.
This morning I checked out the latest master branch and started a
fresh building and everything works perfectly.

The issue should be my local issue (maybe related to some environment
variables or dependent libraries). I'm still keeping my eyes on it,
and will investigate the root cause if it happens again.

Please close this ticket, thanks, appreciate it!
