Control: tags -1 + patch Hello,
I found a patch from Gentoo that could work: Description: Fix ODR violation for IsFloatType_v constexpr is only implicitly inline for functions or static data members, so the two constexpr IsFloatType_v definitions here cause an ODR violation. Explicitly mark as inline constexpr.
