That's not a correct opcode. It seems the 17 bellong to the previous opcode (41 0F A4 D2 17: shld r10d, edx, 0x17) but I don't see in the code why the 17 would not be fetched in the previous opcode.

You are using latest box64?

Oh, it's probably some obfuscated code IIRC, so there must be an invalid opcode somewhere. I need to debug that on my side.
