Subject: [ruby-core:33983] [Ruby 1.9-Bug#4217] irb exits unexpectedly with non-ascii Regexp on Windows

Issue #4217 has been updated by Heesob Park.


I think r30412 is incomplete.

After applying r30412, while the second case is fixed, the first case is still exist.

irb(main):001:0> Regexp.new("\xFF")
