Description

I am new to so many things: Linux, Ruby, bugs.ruby-lang,

'Not sure if anyone here will be able to help, but I'm having trouble with a set of scripts erroring out with a Segmentation fault. Anyone who can lend me a bit of help on this issue, I would really like to hear from. I'm marking this issue as urgent because a business-critical process in the company that I work for is being blocked by it.

It seems that library.1.8.so.1.8.7 is in some sense the source of my trouble, but I'm not sure how to determine:
1.) which precise line is causing the errors.
2.) what steps (package re-installation, etc.) to take to correct the problem.

I'm new enough to Ruby that I don't know whether or not there's a way to run the script(s) in some sort of debugging mode, but if I could figure that out, it might help.

Let me know, if I need to post more information, but here's a bit of info. on the host that I've been running the script from:
