The reason was wrong.  The solution is correct!

Hmm, what was really happening here was this:
    Please store the 4-byte quantity representing the
address of the string "Arf!" into the 1 byte quantity
represented by the variable b.  Since there is no room for
this large quantity, please truncate to fit.

Needless to say, on a VAX under VMS, the first page of
memory (0x00 - 0xff) is off limits to non-priviledged
processes. 

Remember: "Pointers are the root off all evil in C, and also
           the root of all successes!"
