Comment:

 Looks like the error is:

 {{{

 I found a reference to this issue here:
 https://github.com/NixOS/nixpkgs/issues/309365 . It provides a link to the
 intentional llvm change that causes this gcc build failure. There is no
 reference to a gcc bug report. Have you tried a newer version of gcc to
 see if the problem is already fixed? Try the gcc14 or gcc-devel ports.
