RuboCop version

Include the output of rubocop -V or bundle exec rubocop -V if using Bundler.
If you see extension cop versions (e.g. rubocop-performance, rubocop-rspec, and others)
output by rubocop -V, include them as well. Here's an example:

rubocop -V                                                                                                                                                        [9:27:10]
1.25.1 (using Parser 3.1.0.0, rubocop-ast 1.15.1, running on ruby 3.1.0 x86_64-darwin21)

Oh here is the state of the partially corrected file when rubocop crashes

# frozen_string_literal: true

require_relative "tag_cloud/compiler"

module Lab42
  module TagCloud extend self
                  def color_value(color_spec)
                    Compiler.color_value(color_spec.to_s)
                  end
  end

after some tinkering I found out that the extend self in the same line as module triggers this exception

[j-miyake]

I reproduced this problem disabling Style/TrailingBodyOnModule.

The code to reproduce.

module Foo extend Bar
  something
end

# Got this error:
# Infinite loop detected in /path/to/example.rb and caused by Layout/IndentationConsistency -> Layout/IndentationWidth

# Things following the module name doesn't have to be `extend`. This code causes the same error.
#
# module Foo bar
#   something
# end

The autocorrect works with no errors when Style/TrailingBodyOnModule is enabled.

module Foo
  extend Bar
  something
end

Should we fix Layout/IndentationConsistency not to align with the thing just next to the module name, or fix Layout/IndentationWidth to allow aligning with it?

There is the same problem with the class definition when Style/TrailingBodyOnClass is disabled.

class Foo bar
  something
end
