----------------------------------------
Bug #14742: Deadlock when autoloading different constants in the same file from multiple threads
https://bugs.ruby-lang.org/issues/14742
* Author: eugeneius (Eugene Kenny)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.6.0dev (2018-05-08 trunk 63355) [x86_64-darwin17]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
The following example deadlocks consistently:
~~~ ruby
# a.rb
autoload :Foo, __dir__ + "/b"
autoload :Bar, __dir__ + "/b"
t1 = Thread.new { Foo }
t2 = Thread.new { Bar }
t1.join
t2.join
# b.rb
module Foo; end
module Bar; end
~~~

$ ruby a.rb
