Either 20218 is a bug or this is.  It seems to me that 20218 is the bug.

If you declare a function to be hidden, you are asserting that it will be
defined in the current DSO.  From the GCC documentation:

"Two declarations of an object with hidden linkage refer to the same object
if they are in the same shared object."

Calling this function directly is a correct optimization, the bug is that you
fail to define it (by defining the key method) in the same DSO.

If this class is imported from a library, it shouldn't have hidden linkage; the
library's namespace should have explicit default linkage.
