GCC bugzilla is not a place to learn C++, just read the standard, in particular
[class.static.data]/4:
"If a static data member is of const integral or const enumeration type, its
declaration in the class definition can specify a constant-initializer which
shall be an integral constant expression (5.19). In that case, the member can
appear in integral constant expressions within its scope. The member shall
still be defined in a namespace scope if it is used in the program and the
namespace scope definition shall not contain an initializer."

a temporary (of type unsigned) has to be created, and the reference binds to
the temporary, not to test::i
This is invalid, please don't reopen it
