--- Comment #1 from Gaius Mulley <gaius at gcc dot gnu.org> ---
I think the solution is to track the context of valid qualidents kinds during
parsing.  This should be done for constant blocks, type declarations and
variable declarations.  If the error is non recoverable an error message
including an explanation of the context should be emitted before exiting
(without an ICE).

The implementation PR-115957 used a number of boolean variables - these could
be replaced by the state tracking as above - hopefully resulting in cleaner
code.
