Your definition of Image is probably wrong.

You may have missed a pointer (8 bytes).

I'm pretty sure it's correct?

Here's the D version:

https://repo.or.cz/magickd.git/blob/e5d06e939:/source/magickd/core/c/image.d#l751

Here's the C version:

How to test:

in D-land:

import magickd.core.c.image : Image;

pragma(msg, Image.filename.offsetof);

In C-land

#include <stdio.h>
#include <magick/image.h>

int main()
{
   Image *ptr = NULL;
   printf("%ld", &(ptr->filename)); // may need a different specifier
}

If those are not the same, then your struct is off.
