Could you also paste the D version of your code? Perhaps the
compiler (LDC, GDC) will generate similarly

After some debugging, I found out that the p pointer becomes
null at the end instead of pointing to a value. I have no
experience with using in-line assemblers

While I technically finished the 0.2 version of my graphics
engine which has a reasonable speed at low internal resolutions
and with only a couple of sprites, but it still gets bottlenecked
a lot. First I'll throw out the top-down determination
algorhythm as it requires constant memory paging
