--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Inc is a different class in the shared library and the header if you use
-fvisibility=3Dhidden. Since the type of the static variable is hidden stil=
l, the
variable will be still hidden even if it was marked as default visibilitity.
If you want to share Inc across shared libraries and executables, then you =
need
to mark that class as visibility default too.=
