This code crashes compiler when using clang 15.0.0 but compiles fine under newest versions od gcc and msvc
```cpp
#include <cstdio>
#include <cstddef>
struct Test
{
int a = 1;
inline static int sa = 2;
};
template< typename T , typename C , typename L >
consteval size_t GetOffsetOf( T C::* ptr , const L& of ){
C* pClass = nullptr;
return of(pClass);
}
template< typename T , typename L >
consteval const void* GetOffsetOf( const T* ptr , L ){
return ptr;
}
#define GET_OFFSET_OF( Type , Member ) GetOffsetOf( &Type::Member , []<typename T>( T* )->size_t{ return offsetof( T , Member ); } );
int main()
{
constexpr auto V1 = GET_OFFSET_OF( Test, a );
constexpr auto V2 = GET_OFFSET_OF( Test, sa );
printf( "addr: %lld | %lld\n" , (long long)V1 , (long long)V2 );
return 0;
}
```
