Backport #146

Updated by jeremyevans0 (Jeremy Evans) about 1 year ago

=begin 
  
  The second frame's line number appears to always be incorrect when a Proc is created via a non-toplevel method call. 
  This small program and its output illustrate the issue: 
 
  def first # line 1 of proc_caller.rb on my system 
    second 
  end 
 
  def second 
    b = third do 
      1 + 1 
    end 
    return b 
  end 
 
  def third(&b) 
    return b 
  end 
 
  eval("p caller(0)", first) 
 
  Output on recent 1.8 releases, including 1.8.6 and 1.8.7: 
  ["proc_caller.rb:6:in `second'", "proc_caller.rb:6:in `first'", "proc_caller.rb:16"] 
 
  Output that I would expect: (line 6 is in 'second', not 'first') 
  ["proc_caller.rb:6:in `second'", "proc_caller.rb:2:in `first'", "proc_caller.rb:16"] 
 
 =end
