--- Comment #11 from Georg-Johann Lay <gjl at gcc dot gnu.org> ---
This cannot be fixed in GCC as C++ doesn't support ISO/IEC DTR 18037 named
address spaces. This feature requires that the C++ front-end knows about ASes
and handles them properly. This doesn't imply that ASes are exposed on
language level; knowing about ASes "internally" would be sufficient. As it's
pretty much clear that C++ WG21 will never accept such qualifiers (not even the
C WG14) did, just close this as WON'T FIX.
All that can be done is proposing work-arounds: Use "Embedded-C++" coding
convention that avoids VTABLEs, or use a device that can host .rodata in flash
like families -mmcu=avrtiny and -mmcu=avrxmega3.
