Adding the following line at the end of sub BUILD in “MyClass.pm” seems to fix the problem:

Role::Tiny->apply_roles_to_object($self, $module);

So my guess is: roles are, by default, class-based, rather than object-based, so that once a role has been added to a class, the definition of that class doesn’t change. But with multiple threads, the problem doesn’t arise as the class definition is re-created for each new thread.

Hope that helps,
