I could reproduce the linker error.
But:
Clang 3.9 is apparently not standard compliant.
The definition of

static const constexpr Key_value_type MIN_KEY = std::numeric_limits<Key_value_type>::min();
static const constexpr Key_value_type MAX_KEY = std::numeric_limits<Key_value_type>::max();

inside the IOV class is allowed. This should not produce a linker error and also does not produce one on other
compilers. Is clang3.9 so important to justify ifdef'ing with the compiler type and version ?
Remark: This error only happens for C++ 14. C++ 17 seems to be OK.

This

If a static data member is declared constexpr, it is implicitly inline and does not need to be redeclared at namespace scope. This redeclaration without an initializer (formerly required as shown above) is still permitted, but is deprecated. (since c++17)

from https://en.cppreference.com/w/cpp/language/static (constant static members) ?

Maybe clang 3.9 is overly standard compliant?

Minimal example

#include <algorithm>
#include <cstdint>
#include <limits>
#include <iostream>

class IOV
{
public:
  static constexpr std::int64_t MIN_KEY = std::numeric_limits<std::int64_t>::min();
};

//without this in c++14, linking will fail on gcc 9.2.0, clang3.9 (did not test others)
//const std::int64_t IOV::MIN_KEY;
  
int main ()
{
  auto& mini = std::min(IOV::MIN_KEY, std::int64_t(0));
  std::cout << mini  << std::endl;
  return 0;
}
