If a function has rb_warning() that is not a leaf because warning ultimately is a method call of Warning#warn. If a function has rb_name_error() that is not a leaf because NameError is allocated, then initialized. This of course involves calling NameError#initialize. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66976 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
