This worked in 2.058:

inout(T) * foo(T)(inout(T)* t)
{
    static assert(is(T == int *));
    return t;
}

inout(T)* bar(T)(inout(T)* t)
{
    return foo(t);
}

void main()
{
    int *i;
    bar(&i);
}

It fails the assert in the 2.059 beta.

It seems to only happen if 'i' is a pointer, and only if foo is called with an inout variable from an inout function.

Note that the function still compiles ( with typeof(t) == inout(int *)* ), it's
just that the T is not properly extracted using IFTI.  This has consequences if
you use T to create another template.
