That looks like a report of an internally detected error
of soemtihng that should never happen, something that
firefox code or build options should not result in.

As a somewhat confirming note . . .,2.log

is a log from a successful build of 107.0_2,2 on/for
main [so: 14] --thus using a more recent clang++
vintage as well.

Thus, it suggests that "LLVM 13.0.1 from ports" has
a problem that firefox's build ran into.
