----------------------------------------
Bug #13298: mingw SEGV TestEnumerable#test_callcc
https://bugs.ruby-lang.org/issues/13298
* Author: Greg L
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.5.0dev (2017-03-09 trunk 57821) [x64-mingw32]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
First week in January, when I first started building, I had a SEGV in test-all occurring in TestEnumerable#test_callcc. I patched around it, but decided it was time to see if I could find a solution.
The issue occurs in [test/ruby/test_enum.rb:559-570](https://github.com/ruby/ruby/blob/d6873af4bdc99914f20f6184966fa840c91bdf10/test/ruby/test_enum.rb#L559-L570). Below is the code:
```ruby
assert_raise(RuntimeError) do
c = nil
o = Object.new
class << o; self; end.class_eval do
define_method(:<=>) do |x|
callcc {|c2| c ||= c2 }
0
end
end
[o, o].sort_by {|x| x }
c.call
end
```
While trying to determine the problem in a separate test environment, I stumbled across an odd solution.
Add the line `c.to_s` immediately before the `c.call` line. My system no longer stops.
I'd be happy to do a PR, but I can only test on Windows.
Two questions --
1. Might all of tests that involve `callcc` or `Continuation` be moved into another test file? Since it is considered 'obsolete'... I'd be happy to do.
2. Rather odd that this fixes the issue. Any ideas?
