char[10] f()
{
    char[10] x;
    return x;
}

string g()
{
    return f();
}

This compiles, but it shouldn't as g() will point to garbage.

I noticed this when using std.digest.sha:

string foo(string s)
{
    import std.digest.sha;
    return s.sha1Of.toHexString;
}

toHexString returns a char[N], so foo() returns garbage because of this bug.
