After typing the close brace, I get the following:
c-parse-state inconsistency at 3: using cache: (2), from scratch: nil.
POINT-MIN: 1
Old state:
(setq c-state-cache '(2) c-state-cache-good-pos 1 c-state-nonlit-pos-cache

nil c-state-old-cpp-end nil c-parse-state-point 3)
I have not noticed any indentation errors due to this, but any cache
inconsistency might lead to errors down the line, hence this report.

Thank you for the testing! I have now committed the patch, and I am
closing the bug with this post.
