Just got this on the spidermonkey bindings. Will minimize with creduce.

[emilio]

@fitzgen does this reproduce with #360?

[fitzgen]

Reduced test case:

namespace JS {
template <typename> class PersistentRooted;
}
template <typename> class a { a *b; };
namespace JS {
template <typename c> class PersistentRooted : a<PersistentRooted<c>> {};
}

@emilio I'll give it a try when I get into the office.

[emilio]

It's the same issue, I'll include the test case. (That C++ is nasty btw :P)
