Description

« Hide

Consider the following example:

[1, 2, 3].freeze.instance_eval { initialize }

On JRuby, this basically clears the frozen array.

On the latest MRI 1.8.6, the code above leads to TypeError.

This also leads to a rubyspec failure for Array.

The proposed patch (with regression test) fixes the problem.
