Gentlemen!

An old bug in the patch is causing compiler-warnings, and leads to 
erroneous behavior where pointers are bigger than 32-bit.

Moreover, given the memcpy right after it, the bzero is simply not 
needed at all. Instead of removing the bogus ampersand, the entire line 
should be deleted. (I would've replaced the memcpy with an assignment 
too, but that's not as pressing.)

Can I commit this?
