>From emacs -Q:
Load the attached file (inline). Turn on parse state debugging:
M-x c-toggle-parse-state-debug RET
Navigate to the uint8_t:
C-s 8
Delete the 8 and start to replace it:
<backspace> 1
At this point I get a cache inconsistency warning:
c-parse-state inconsistency at 179: using cache: nil, from scratch: (145).
POINT-MIN: 1
Old state:

This inconsistency has not yet caused incorrect editing behavior (that I
have noticed, but I know that any cache problem has the possibility of
causing problems down the line.

OK, that's three days, now, with no further problems. So I'm closing the
bug with this post.
