The assert in "foo" passes, which it obviously shouldn't.

inout(char)[] bar (inout(char)[] a)
{
    return a;
}

void foo (string str)
{
    string result;
    result ~= bar(str);
    assert(result == "!");
}

void main ()
{
    foo("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
}

If I remove "inout" in "bar" or the append in "foo" the code work as expected.
What "result" will actually be depends on the length of the string passed to
"foo".

I've only tried this with on Mac OS X, both 32 and 64bit.
