[cfe-users] Unexpected (IMO) constant-conversion warning

[Szymon Zimnowoda via cfe-users]

 Hello, consider following code:
https://godbolt.org/g/UN8xTy <https://godbolt.org/g/n3Rt9D>

I do not understand, why overflow warning is here, there is no explicite
int in this code.
When removing constexpr, warning disappears, when changing to:

static constexpr uint8_t b = uint8_t{~a};

warning disappears.

Could someone explain it to me?
