kimgr added a comment. > When using a PCH, tokens are skipped until after the through header is seen.
I know this is what MSVC does (though in their case I think it's an artifact of their implementation), but I remember this being a source of mysterious bugs: #define MY_SYMBOL 1 #include "stdafx.h" // include pch The `#define` would silently disappear, and the symbol would never be defined. I wonder if it would be worth adding a warning for this in `SkipTokensUntilPCHThroughHeader`?
