            Bug ID: 36288
           Summary: Merge clang r324419 into 6.0 branch: [Lex] Fix
                    handling numerical literals ending with ' and signed
                    exponent.

          Hardware: PC
                OS: All

This commit https://reviews.llvm.org/rC324419 fixes crash for invalid usage of
digit separator introduced in C++14. The main reason to merge the fix is that
it fixes OSS-Fuzz bug
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=4588 which is classified
as security issue. Regardless of their own security evaluations, I think clang
vendors and users will benefit from this fix.
