Yes, we've refactored this quite a bit for auctex 13 in order to be able
to use lexical-binding as mentioned in (info "(auctex) Changes").

If you can with a minimal config, a minimal test file, and a
reproduction recipe, that would be enough, I think.

That would mean that in between `match-string' in 553 and
`replace-match' in 568, something else changed the match data.  But we
use `save-match-data' when calling the expansion function, so in theory
that must not happen.
