I have seen this as well. The reason I have documented the one I have
is that I have been able to recreate it fairly regularly, and I am
hoping that the underlying cause is similar.

Definitely not. I don't recall all the performance problems the caching
code was added to support, but they were very real, and there were a
fair number of complaints because of them. I applaud the work Alan has
done to attempt to improve cc-mode, although I do worry about the
complexity of the current system.
That said, I will file a bug every time I find a new indentation
problem after a new cc-mode update, whether or not I can recreate it,
especially now that we are in pre-release. I want to make sure that
people using Emacs after the release don't encounter the same problems I
am encountering.
