=begin
By aliasing Class.new, one can get around the lack of MatchData.new (and presumably other hidden new methods). If one uses this to try and create a new MatchData, and then calls an instance method of the new MatchData object, Ruby segfaults. This has been tested and reproduced on Ruby 1.8.6p111 and Ruby 1.8.6 HEAD.

=begin
It is reproducible without alias:

% ruby-1.8 -ve 'MatchData.allocate.pre_match'

-e:1: [BUG] Segmentation fault
