https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80485 --- Comment #7 from Tony E Lewis --- Ah yes - I'm seeing it compiling cleanly now on Godbolt's trunk (9.0.0 20180615). Must have been a temporary glitch in the build (and couldn't possibly have been due to my error :P ).

I don't see that. This compiles fine with trunk:
struct dummy {
void nonnull() {};
};
typedef void (dummy::*safe_bool)();
constexpr safe_bool a = ::nonnull;
static_assert( static_cast( a ), "" );
int main () { return 0; }

Thanks to all for all work on this.
(Apologies if this isn't helpful but just in case it is...) I notice that the
original Godbolt snippet ( https://godbolt.org/g/JnrZss ) has regressed from a
rejects-valid in 8.1 to an ICE on trunk ("9.0.0 20180610") :
