--- Comment #4 from Orgad Shaneh <orgads at gmail dot com> ---
In field::loc_bitpos, m_loc_kind is FIELD_LOC_KIND_PHYSNAME (3). m_name is
m_MsgIdx.

The field is a static field in a class. Its type is a typedef of
std::atomic<unsigned int> derivative.

Something like this (notice it *doesn't reproduce* with this example):

#include <atomic>

template<typename T>
struct ac_atomic:public std::atomic<T>
{
    ac_atomic(T value =3D 0) : std::atomic<T>(value) {}
    using std::atomic<T>::operator=3D;
};

typedef ac_atomic<unsigned int> ac_atomic_uint;

class Foo
{
public:
    static ac_atomic_uint m_MsgIdx;
    const char *Bar;
};

enum class E { V1, V2 };

static void CheckField(const char* Foo::*StrField, E Enum)
{
}

int main() {
    CheckField(&Foo::Bar, E::V1); // Break here and execute "step"
}
