I found myself starting to get confused with:

Code:

_len    dw   ?

....and then....

Code:

mov dword [_len], ecx

....which is wrong. Laughing

Just because of the first two alphabets "dw" look identical.

What's yours?

When using a stack frame I'll play with position of RSP and then forget I'm using RBP to reference parameters (which are no longer in the same place). It's hidden in macros so I don't feel so bad about doing it, but it wastes a trip to the debugger to remind me sometimes. (I could just fix the RSP register back to where it was, but there is no need when the frame clean-up will fix it.)

* I don't know if I do this the most - it just happened and is fresh in my mind. Razz
