I figured out that #NAME# resolving has been changed to reuse record field value resolving by adding NAME as a standard field. With a two-level multiclasses and both with #NAME#, the trunk code runs into infinite recursion. This patch fixes this issue by skipping re-calculating NAME when we found NAME is changed and skip resolving the field if it's the same as the specified one to be against.
