I tried to build a class with a private function

pam_response** resp, void* appdata_ptr) to extern (C) int
function(int, const(pam_message**), pam_response**, void*)* is
deprecated
```
And when I start up, at the moment of calling the
authentication function, I get `Segmentation fault`.
Is the function identified differently in the class? How can
this be fixed?
Of course it segfaults, you are trying to give delegate
pretending it is to be a standalone function.
For example you can fix it by using a trampoline - Make a global
class instance somewhere, make conversation_func static (if you
absolutely want it to be in class) and then in that function use
instance.actual_conversation_func, that will do actual work.
Maybe other solutions exists that is not variation of this method
by I can't come up with anything else.
