Do I understand correctly that loader will set up the address of stub for
non-implemented functions which are directly required by a module/dll (i.e.
NtExtendSection).
So, in this case application will crash when calling such stub.

However, if module/dll not required particular non-implemented function then 
GetProcAddress() will return NULL for corresponding name?

Is it right?
