Hi!
I noticed a regression in the coverage library. I tried to write a minimal =
program to show it, hopefully it gives some clues or where the issue might =
lie.
In ruby 2.5.8 and earlier, the following program would print `{:lines=3D>[1=
, 1, nil]}`, showing that the body of the "foo" method was run once. Howeve=
r, on newer rubies, it prints `{:lines=3D>[1, 0, nil]}`, which is incorrect=
because the "foo" method body has actually been run once.
This is the repro script:
```ruby
# frozen_string_literal: true
require "coverage"
Coverage.start(lines: true)
code =3D <<~RUBY
def foo
"LOL"
end
RUBY
File.open("foo.rb", "w") { |f| f.write(code) }
require_relative "foo"
TracePoint.new(:line) do |_tp|
foo
end.enable do
sleep 0
end
res =3D Coverage.result
puts res[File.expand_path("foo.rb")]
```
