Bug #3118
closedbackport r25230 and r25995 to fix segfault
Description
=begin
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.
