There's some unfortunate ODR violations that get dianosed with GCC but not Clang
for static inline constexpr variables defined inside the class body:
template<typename T>
struct static_const
{
static JSON_INLINE_VARIABLE constexpr T value{};
};
This can be ignored pretty much. There is the same problem for std::piecewise_construct:

Instead of specifying env variables all the time
we can instead embed the __asan_default_options symbol
in all executables / shared objects. This reduces code
duplication.
