Issue #9344 has been reported by thyresias (Thierry Lambert).

----------------------------------------
Bug #9344: warning origin incorrect with instance_eval
https://bugs.ruby-lang.org/issues/9344

Author: thyresias (Thierry Lambert)
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 1.9.3p484 (2013-11-22) [i386-mingw32]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN


File 'test.rb' contains:
  $-w = 2
  code = <<-RUBY
    x = /]]/
    y = /[a-z]+*/
  RUBY
  instance_eval code, 'foo.rb'

The execution reports:
  foo.rb:1: warning: regular expression has ']' without escape: /]]/
  test.rb:6: warning: nested repeat operator + and * was replaced with '*': /[a-z]+*/

The last line should state 'foo.rb:2' instead of 'test.rb:6'.

The bug is also present in: ruby 2.0.0p353 (2013-11-22) [i386-mingw32]
