--- Comment #11 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Division by zero is undefined behavior for fixed-point types the same way 
as it is for integer types (but not floating point, at least when 
infinities and NaN are supported).  Treating it like integer division in 
the compiler would seem reasonable.
