Subject: [ruby-core:64504] [ruby-trunk - Bug #10133] Bug in ruby

Issue #10133 has been updated by Liz Huang.




When I wrap my code by thread, it has trouble to finish. I only see the output
of "Started At ....",  never get to see "End at ...".

require 'fiddle/import'

  module Libm
    extend Fiddle::Importer
    dlload '/Library/WebServer/smart/lib/libsamplesize.dylib'
    extern 'long Calculate(long, double, double, char*)'
  end

  puts "Started At #{Time.now}"
  errmsg = "                                                                                " 
  thr1=Thread.new{ puts Libm.Calculate( 1000, 0.2, 0.9, errmsg)}
  #thr2=Thread.new{ puts Libm.Calculate( 800, 0.3, 0.9, errmsg)}
  thr1.join
  #thr2.join
  puts "End at #{Time.now}"

Bug #10133: Bug in ruby
https://bugs.ruby-lang.org/issues/10133#change-48449

* Author: Liz Huang
* Status: Third Party's Issue
* Priority: Normal
* Assignee: 
* Category:

* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------

I got a new Mac Pro server and tried to upgrade web applets to new version of Ruby On Rails, the web applet calls an external Fortran library I developed, it worked in Ruby on Rails (Ruby 1.8.7 and Rails 2.3.18) by using "DL". I tried to develop the same web applet in Ruby on Rails 4 (ruby 2.1.0p0 (2013-12-25 revision 44422) and Rails 4.1.2), with "DL" deprecated, so I use fiddle and wrapped Fortran by C, I tested the interface by commenting out all computation parts first to make sure it is working. Now I have the computation codes back (same codes as in older version) and I even create a console application to test the code is working. But when I try to call it from Ruby, it crashed.
I saved all messages in terminal window in attached file "bug.rtf" and also send the crash report.
I feel it might a bug in Ruby as it works in older version and the Fortran codes was tested in console application project.
