Subject: [ruby-core:32953] [Ruby 1.9-Bug#4001][Open] RubyVM::InstructionSequence.compile can not take the 5th argument

Bug #4001: RubyVM::InstructionSequence.compile can not take the 5th argument
http://redmine.ruby-lang.org/issues/show/4001

Author: Yutaka HARA
Status: Open, Priority: Normal
Assigned to: Koichi Sasada, Category: YARV
ruby -v: 1.9.2p0

InstructionSequence.compile takes src, file, path, line, opt
as the arguments, but raises ArgumentError when opt is given.

Example:

  $ ruby -e 'p RubyVM::InstructionSequence.compile("", "", "", 1, {})'
  -e:1:in `compile': wrong number of arguments (5 for 1..4) (ArgumentError)
