           Summary: writefln() is duplicating values for parameters supplied
           Product: D

I'm not sure if it's just something I did wrong, but I'm getting the wrong
value output from writefln.

template
MakeFourCharCode(char[] inS)
{
        static assert(inS.length == 4);
        const FourCharCode MakeFourCharCode = (inS[0] << 24)
                                                                        |
(inS[1] << 16)
                                                                        |
(inS[2] << 8)
                                                                        |
inS[3];
}


char[]
FourCharCodeAsString(FourCharCode inVal)
{
        char[4] s;

        s[0] = (inVal >> 24 & 0xFF);
        s[1] = (inVal >> 16 & 0xFF);
        s[2] = (inVal >> 8 & 0xFF);
        s[3] = (inVal >> 0 & 0xFF);

        return s;
}

foo()
{
        FourCharCode val1 = MakeFourCharCode!("cntl");
        uint val2 = 4;
        writefln("SketchViewDrawHandler called. Class: '%s', Kind: %s ('%s')",
                        FourCharCodeAsString(val1),
                        val2,
                        FourCharCodeAsString(MakeFourCharCode!("abcd")));
}

Output of foo:

SketchViewDrawHandler called. Class: 'cntl', Kind: 4 ('cntl')

I expected:

SketchViewDrawHandler called. Class: 'cntl', Kind: 4 ('abcd')

(I originally had put val2 as the argument where "abcd" is, with appropriate
casting, but then I switched to "abcd" as an experiment).
