--- Comment #3 from Pavel I. Kryukov <pavel.kryukov at phystech dot edu> ---
I faced the problem because Clang-Tidy warns about possible uncaught exception
if I initialize a global static string_view variable.
It seems that Clang-Tidy simply checks whether `noexcept` is specified, is it a
Clang-Tidy problem then?

Command line output:

clang-tidy-5.0 -checks=cert-err58-cpp gcc_string_view.cpp -- --std=c++17

1 warning generated.
