Reduced example:

struct lr1 {
    lr1* a;
}
template proxy(T) {
    static if (is(typeof(gen!T.str)))
        enum str = gen!T.str;
}
template gen(T) if (is(T == struct)) {
    enum str = T.stringof;
    private enum xstr = gen!(lr1*).str;
}
template gen(T: S*, S) {
    private alias rc = proxy!S;
    //pragma(msg, __traits(allMembers, rc)); <- uncomment this line resolves
error
    enum str = rc.str~"_ptr";
}
enum tmp = proxy!lr1.str;
