I have:
main.cpp: In function 'QString parityToString(ParityType)':
main.cpp:312: warning: control reaches end of non-void function
When:
enum ParityType 
{
    PAR_NONE,
    PAR_ODD,
    PAR_EVEN,
    PAR_MARK,               //WINDOWS ONLY
    PAR_SPACE
};
And my function:
QString parityToString(ParityType value)
{
        switch(value)
        {
                case PAR_NONE:
                        return "none";
                case PAR_ODD:
                        return "odd";
                case PAR_EVEN:
                        return "even";
                case PAR_MARK:
                        return "mark";
                case PAR_SPACE:
                        return "space";
        }
}

Can you provide a preprocessed testcase?

My test case:

enum ParityType 
{
    PAR_NONE,
    PAR_ODD,
    PAR_EVEN,
    PAR_MARK,               //WINDOWS ONLY
    PAR_SPACE
};
QString parityToString(ParityType value)
{
        switch(value)
        {
                case PAR_NONE:
                        return "none";
                case PAR_ODD:
                        return "odd";
                case PAR_EVEN:
                        return "even";
                case PAR_MARK:

(In reply to comment #2)
> My test case:

That testcase is not compilable at all.  Can you use -save-temps and provide
the preprocessed source (which is the .ii file that is generated)?

The URL for preprocessed source gives a 404 now.

The enum has a range 0-7 and if you call parityToString(ParityType(5)) then
control falls off the end of the function, so the warning is correct.
