[ruby-core:51303] [ruby-trunk - Bug #7672][Open] Segmentation faults with ibm_db gem on three versions of 1.9.3 on MacOS X and Ubuntu

Bug #7672: Segmentation faults with ibm_db gem on three versions of 1.9.3 on MacOS X and Ubuntu
https://bugs.ruby-lang.org/issues/7672

Author: kgerrard (Ken Gerrard)

Target version: 
ruby -v: 1.9.3


=begin
I have a DB2-backed Rails 3.1 project I’m looking to update to 3.2, which means I have to use a newer version of the ibm_db gem. I have no problem running a server with the newer gem, but the intensive Cucumber tests inevitably result in a segmentation fault. I can detect no pattern to where the crashes occur. 

I’m posting here ((<as recommended by Praveen Devarao at the ibm_db help forum|URL:http://rubyforge.org/forum/forum.php?thread_id=51204&forum_id=9503>)). I’m hesitant because I read the ((<HowToReport|URL:http://bugs.ruby-lang.org/projects/ruby/wiki/HowToReport>)) page and I don’t have reproducing code as required, since the segmentation faults happen in different places.

Sometimes instead of a segmentation fault, the process just hangs indefinitely.

I’ve gathered and attached logs from all combinations of the following:
* OSes: MacOS X 10.8.2, Ubuntu 12.10
* Ruby 1.9.3: p194, p286, p327
* ibm_db gem: 2.5.9, 2.5.11

Looks like I can’t attach more than ten files at once, I’ll attach the MacOS logs separately.

I also have Ubuntu core dumps if that helps, too big to attach.

Here is a sampling of crashes under 1.9.3-p194 on MacOS X:

In case the above is inadequate, the outputs of (({ruby -v})) for each version on each OS:

MacOS X:
* (({ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin12.2.1]}))
* (({ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-darwin12.2.1]}))
* (({ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-darwin12.2.1]}))

Ubuntu:
* (({ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]}))
* (({ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-linux]}))
* (({ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-linux]}))

Let me know if you need anything else! I’m definitely available to provide further logs and whatever is necessary to work through this.
