There are two important points about C and assembler. First, the named 
locations (and un-named internal locations like function return 
addresses) are *contiguous*. Giving a user access to one block may give 
a user access to other blocks if one is not careful. The other is that 
the typing is in the code and compiler, but not in the runtime memory. 
So text input can be read as code and a return jump address to the bytes 
interpreted as code.
