This looks promising:

   https://github.com/abseil/abseil-cpp/commit/e8c1a5ff2346d40be5f2450044c01c845777cc02

   Fix check_op(s) compilation failures on gcc 8 which eagerly tries to
   instantiate std::underlying_type for non-num types.

   Before cpp20 using std::underlying_t on non enum types is undefined behaviour.


Given that the build failure is for gcc 7.5 - don't have a version so old
to test...



Cheers,
