Subject: [ruby-core:64479] [ruby-trunk - Bug #10133] Bug in ruby

Issue #10133 has been updated by Liz Huang.

File calculateSamplesize.rb added
File libsamplesize.dylib added

I tested my code in Ruby script and it works fine when I run the following in irb:

load "calculateSamplesize.rb"
ss=Samplesize.new()
ss.compute()

I attached calculateSamplesize.rb and libsamplesize.dylib, it seems this bug only shows up
in Ruby On Rails, I don't know how to fix...

----------------------------------------

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.
