Add a frozenness check to Enumerator#initialize.
* enumerator.c (enumerator_init): Add a frozenness check to prevent a frozen Enumerator object from being reinitialized with a different enumerable object. This is the least we should do, and more fixes will follow. [Fixes GH-368] Patch by Kenichi Kamiya. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
