Bug #5270: Date#freeze causes memoized Date methods to fail
http://redmine.ruby-lang.org/issues/5270

Target version: 
ruby -v: ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin10.8.0]


When freezing a Date object, memoized methods will fail because the memoized value cannot be stored on the frozen object. This is because memoized values are stored as instance variables on the object, and those are immutable for frozen objects.

Attached to this bug report is a test case, as well as a patch that fixes the issue (and also includes the test case).
