If "unsigned char" is too big, what about *(char *)$esp@300?
"char" is better, but not because of the length.

However, what I really meant is to ask whether *$esp should indeed
refuse to work, or is that a bug?
I imagine it must have worked at one time... 

If we-all think now that it's okay for *$esp not to work, then let's
fix the docs and be done.

I think the reason it doesn't work now is that it's typed as a void pointer.

(gdb) pt $esp
type = void *

Probably it used to be typed as a char * or something.
