================ Comment at: clang/lib/Parse/ParseDeclCXX.cpp:1055 + // semi-colon. + EndLoc = PP.getLastCachedTokenLocation(); + } ---------------- It seems to me that either `EndLoc` was miscomputed and should already point to the last token that we skipped over, in which case we should fix `ParseDecltypeSpecifier` to return the correct source location, or `EndLoc` is correct and we should revert back to the corresponding token and only annotate that portion of the token stream as the decltype specifier. (Or maybe a third option: `EndLoc` is meaningless when the type specifier is erroneous, in which case this code is still wrong because it's using that value in the case where backtracking is not enabled.) Rolling back the token stream to the token corresponding to `EndLoc` seems likely to give us the best error recovery here, assuming that `EndLoc` is currently set to the token that we think is the last one that's intended to be part of the decltype specifier.
