I still think it’s a bug, but fairly easy to avoid: either properly construct APF2, or avoid assignment.
It's an issue that's intrinsic to how unions interact with constructors, I think. The standard even mentions it:
"Note: In general, one must use explicit destructor calls andplacement new-expression to change the active member of a union."
Cheers.
