.. title:: clang-tidy - cppcoreguidelines-interfaces-global-init

cppcoreguidelines-interfaces-global-init
========================================

This check flags initializers of globals that access extern objects,
and therefore can lead to order-of-initialization problems.

This check implements `I.22
<https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ri-global-init>`_
from the C++ Core Guidelines.

Note that currently this does not flag calls to non-constexpr functions, and
therefore globals could still be accessed from functions themselves.
