Infinite loop on Layout/EndAlignment (with EnforcedStyleAlignWith: variable)

[Drowze]

Expected behavior

I expect Rubocop to autocorrect my code (or at least not crash while trying to do so).

Actual behavior

When running Layout/EndAlignment's autocorrection (with EnforcedStyleAlignWith: variable on that cop), Rubocop raises an infinite loop error.

Steps to reproduce the problem

Given .rubocop.yml:

AllCops:
  NewCops: disable

Layout/EndAlignment:
  EnforcedStyleAlignWith: variable

And a file test.rb:

100.minutes - if rand(100) > 50
                30
              else
                50
              end.minutes

When I run rubocop --only Layout/EndAlignment --debug -a test.rb I get:
