I believe this is a false positive: https://bugs.webkit.org/show_bug.cgi?id=109579#c12 I have this: enum { MarkedState, UnmarkedState } m_markState and it reports the following: enum members should use InterCaps with an initial capital letter. [readability/enum_casing] [4] I was trying to solve this, but I give up after created a test-case in cpp_unittest.py with exactly the same code, and it was passing.
We haven't managed to reproduce it on ToT. I assume it was already fixed.
