Description

I found the following issue:

https://travis-ci.org/ioquatix/build-files/jobs/140181966

/home/travis/.rvm/rubies/ruby-head/lib/ruby/2.4.0/forwardable.rb:200:in `compile': negative array size (or size too big) (ArgumentError)
	from /home/travis/.rvm/rubies/ruby-head/lib/ruby/2.4.0/forwardable.rb:200:in `_delegator_method'
	from /home/travis/.rvm/rubies/ruby-head/lib/ruby/2.4.0/forwardable.rb:178:in `def_instance_delegator'
	from /home/travis/.rvm/rubies/ruby-head/lib/ruby/2.4.0/forwardable.rb:154:in `block in def_instance_delegators'
	from /home/travis/.rvm/rubies/ruby-head/lib/ruby/2.4.0/forwardable.rb:153:in `each'
	from /home/travis/.rvm/rubies/ruby-head/lib/ruby/2.4.0/forwardable.rb:153:in `def_instance_delegators'
	from /home/travis/build/ioquatix/build-files/lib/build/files/state.rb:71:in `<class:State>'

This is caused by the following line:

		class State < Files::List
			extend Forwardable
			def_delegators :@files, :each, :roots, :count

It was fine in 2.3.0 and before.

I couldn't reproduce it with r55504 on OS X 11.11.5 and Ubuntu 16.04.

Here's the repro (OS X 10.11.5 / FreeBSD 10.2):

require 'coverage'
require 'forwardable'

Coverage.start

class Fail
 extend Forwardable

 def_delegator :foo, :bar
end

Applied in changeset r55509.


Coverage on non-positive lines

  • compile.c (ADD_TRACE): ignore trace instruction on non-positive
    line.
  • parse.y (coverage): get rid of ArgumentError when the starting
    line number is not positive. [ruby-core:76141] [Bug #12517]
