Hi anon, you have two problems. The first is that, as you've probably noticed, your loop isn't getting executed.

The second problem is that you have some pointer/value-pointed-to confusion.

Try opening up your program in gdb and `define` the macro:
stepi
info reg
x/20i memset32
to step through memset32.

Fix your fucking memset you goon

>at&t syntax

Anyway OP you're telling your memset to copy a dword instead of a byte.

Why not use SSE (Streaming SIMD)? set 256 bits at a time.

I mean, they are giving us this great tool... why not use it?
