--- Comment #7 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Passing a variable-size struct or union by value to a non-nested function 
seems very questionable (the function couldn't be declared with a matching 
prototype), but perhaps that doesn't answer the question because the 
cast-to-union case might appear for a nested function as well.
