--- Comment #5 from Sebastian "spaetz" Spaeth <Sebastian at SSpaeth dot de> --- I fully understand that nobody wants to invest time into fixing this. What would be nice though, is if this were really just a missed optimization and not rejecting to compile valid code. powerpc could ignore the constexpr in this case, rather than failing to build?
