Issue #13485 has been updated by MSP-Greg (Greg L). Not sure about what/when/where, but this test is passing and there is no longer a patch in ruby-loco. Hence, ok to close. Sorry. ---------------------------------------- Bug #13485: MinGW TestEnumerable#test_callcc SEGV info https://bugs.ruby-lang.org/issues/13485#change-100701 * Author: MSP-Greg (Greg L) * Status: Open * Priority: Normal * ruby -v: ruby 2.5.0dev (2017-04-18 trunk 58397) [x64-mingw32] * Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN ---------------------------------------- Re the patch needed in MinGW builds for [TestEnumerable#test_callcc](https://github.com/ruby/ruby/blob/d6873af4bdc99914f20f6184966fa840c91bdf10/t...) (file `test/ruby/test_enum.rb`), I ran the following code with `--disable-gems`: ```ruby require_relative '<path to ruby>/lib/ruby/2.5.0/x64-mingw32/continuation.so' 1000.times { c = nil o = Object.new class << o; self; end.class_eval do define_method(:<=>) do |x| callcc {|c2| c ||= c2 } 0 end end ary = [o,o] begin ary.sort_by {|x| x } c.to_s ; c.call rescue end } ``` Attached is a file with the code and the SEGV output when running. I removed the ruby path to shorten it. Note that if the line - ```ruby c.to_s ; c.call ``` is replaced with - ```ruby c.call ``` my system hangs/stops. No output, no response; have to force the command window closed... ---Files-------------------------------- TestEnumerable#call_cc_SEGV.txt (4.01 KB) -- https://bugs.ruby-lang.org/
