warning: passing NULL to non-pointer argument 1 of 'nullable<T>::nullable(T) [with T = long long int]' (CON-1890)

[lboue]

Describe the bug
I am getting a warning:

warning: passing NULL to non-pointer argument 1 of `'nullable<T>::nullable(T) [with T = long long int]')

Would it be possible to correct this for future versions?
