I'll agree that it isn't what I *expected* but it is *correct*.
Here are some other correct implementations:

 * Compiler refuses to compile the program
 * Program aborts when executed
 * Program runs `rogue'
 * Program assigs 3 to memory location 0xffff8e20

Remember, dereferencing a hard-coded address (in C) has
implementation-defined effect.

In the meanwhile, I agree that the one it chose is non-intuitive.

Followups to `comp.lang.c' and `comp.sys.m68k'.
