debugger start from wrong line.

[zw963]

Example:

# foo.cr

require "yaml"

module Procodile
  struct GlobalOption
    include YAML::Serializable

    @env : Hash(String, String)
    @app_name : String

    def initialize(@env, @app_name, @processes)
    end
  end

  debugger
end

when run debugger like this:

$: crystal i foo.cr

get following output:

    1: require "yaml"
    2: 
 => 3: module Procodile
    4:   struct GlobalOption
    5:     include YAML::Serializable
    6: 
    7:     @env : Hash(String, String)
    8:     @app_name : String
