This code:

module test;

struct struc
{
    struct fnb {}
}

struc fna()
{
    struct fnb
    {
        static void fnc()
        {
            static struct x {}
            pragma(msg,x.mangleof);
        }
    }
    return struc();
}

struc.fnb fna()
{
    static void fnc()
    {
        static struct x {}
        pragma(msg,x.mangleof);
    }
    return struc.fnb();
}

outputs with "dmd -c test.d"

S4test3fnaFZS4test5struc3fnb3fncFZv1x S4test3fnaFZS4test5struc3fnb3fncFZv1x

so both functions fnc have the same mangled name.

This seems like a very constructed situation, but it just illustrates that std.demangle cannot create correct output for local functions if the outer function returns a qualified type. This happens because there is no seperator between the return type and the identifier of the local symbol name.

As a result, local functions might not show up correctly in call stacks.
