d6e582e21ceec768aa72e857c10ba80cad2f2202 by Abseil Team <absl-team@google.com>:
adds bounds-checking for the second range in absl::c_mismatch
The API for the two-range absl::c_mismatch is misleading as it
doesn't check the bounds of the second range against the first one.
This commit cleans up the internals of the overload to make sure that
buggy calls are not exploitable; non-buggy calls are unaffected.
This is consistent with both C++14's two-range std::mismatch and
C++20's std::ranges::mismatch (see http://wg21.link/mismatch).
