Comment:

 Problem is in lib/irb/source.rb, line 75.

 {{{
         @code_block = !parse.nil? && !@in_string && !@in_regexp &&
 !@in_array
 }}}

 These ivars have not been created yet, and if used in a conditional as is
 with warnings enabled, a warning will be raised. I verified with a similar
 snippet with MRI.

 {{{
 $ ruby -e 'foo=!@foo&&!@bar'
 $ ruby -w -e 'foo=!@foo&&!@bar'
 -e:1: warning: instance variable @foo not initialized
 -e:1: warning: instance variable @bar not initialized
 }}}
