From: Matthew Kent Date: 2010-04-10T02:45:14+09:00 Subject: [ruby-core:29393] [Backport #3118] backport r25230 and r25995 to fix segfault Backport #3118: backport r25230 and r25995 to fix segfault http://redmine.ruby-lang.org/issues/show/3118 Author: Matthew Kent Status: Open, Priority: High Assigned to: Kirk Haines Spent some time tracking down a segfault introduced in newer versions of 1.8.6. mkent@el-test:~/git/matzruby (p306)$ ruby -v ~/open4_segfault.rb ruby 1.8.6 (2010-02-05 patchlevel 399) [x86_64-linux] 1000 calls /home/mkent/.gem/ruby/1.8/gems/open4-1.0.1/lib/open4.rb:52: [BUG] Segmentation fault ruby 1.8.6 (2010-02-05) [x86_64-linux] Aborted After much testing it seems the changes introduced in 1.8.6 p306 are at fault as p305 and earlier don't exhibit the problem. As 1.8.7 p174 and up work fine I've identified the following changes that correct the issue: http://redmine.ruby-lang.org/repositories/revision/ruby-18?rev=25230 http://redmine.ruby-lang.org/repositories/revision/ruby-18?rev=25995 also requires http://redmine.ruby-lang.org/repositories/revision/ruby-18?rev=16015 after which the example I've enclosed can do 200,000 calls without issue. ---------------------------------------- http://redmine.ruby-lang.org
