That doesn't look right to me. You're replacing a pointer with a byte? It looks to me like what it really wants to be doing is something like: Pic *p = sys_mem_alloc(sizeof(Pic)); p->data = sys_mem_alloc(size);
amd64 team: Please confirm and de-keyword if necessary.
Created attachment 197026 [details, diff] cdogs-sdl-0.4-64bit.patch I think this works, and makes it easier to understand what's supposed to happen (The data pointer was misleading).
Fixed, thanks.
