Hey Lenard,
Can you build SDL with mingw in a way that the inlined assembly won't be used? (i.e. so that it uses the same source that VisualC does to build)

No mmx/sse instructions are used when source and destination are identical. Just a string move, "rep movsl". I isolated the reverse copy code in a simple C program. It is attached. There is definitely something wrong, though I don't know yet. It appears to run just fine unless I redirect output, then it hangs. Comment out SDL_revcpy and it runs to completion. So something is being stomped.
