Warns when objects which are supposed to be globally unique might get duplicated
when built into a shared library.
If an object with hidden visibility is built into a shared library, each instance
of the library will get its own copy. This can cause very subtle bugs if there was
only supposed to be one copy of the object in question: singletons aren't single,
changes to one object won't affect the others, the object's initializer will run
once per copy, etc.
Specifically, this warning fires when it detects an object which:
1. Appears in a header file (so it might get compiled into multiple libaries), and
2. Has external linkage (otherwise it's supposed to be duplicated), and
3. Has hidden visibility.
As well as one of the following:
1. The object is mutable, or
2. The object's initializer definitely has side effects.
The warning is best resolved by making the object ``const`` (if possible), or by explicitly
giving the object non-hidden visibility, e.g. using ``__attribute((visibility("default")))``.
Note that all levels of a pointer variable must be constant; ``const int*`` will
trigger the warning because the pointer itself is mutable.
This warning is currently disabled on Windows since it uses import/export rules
instead of visibility.
