PiperOrigin-RevId: 292550551 -- 09fbbe73833478d3f26f3e33c8291b991fd3be51 by Derek Mauro : Add a debug bounds-check to absl::string_view::operator[] string_view accesses that are out-of-bounds are undefined behavior: https://en.cppreference.com/w/cpp/string/basic_string_view/operator_at This change causes code to abort in debug mode, indicating a bug and possibly a security issue like a buffer overflow. Code broken by this change should be investigated. PiperOrigin-RevId: 292544735 -- bf2c19cb45682628f963d4067c0cd6deed7e656d by Derek Mauro : Add debug assertions to absl::string_view::front and absl::string_view::back Calling front() or back() on an empty string_view is undefined behavior. This assertion is to help catch broken code. https://en.cppreference.com/w/cpp/string/basic_string_view/front https://en.cppreference.com/w/cpp/string/basic_string_view/back PiperOrigin-RevId: 292453255 -- 47f573679b322f8c0fd2cb037cc87e7bc822ac6b by Xiaoyi Zhang : Release functional/CMakeList.txt.
