Open Object Rexx Interpreter Version 3.1.1 for
OpenSuSE 9.3 (so says System admin)
22.214.171.124-21.14-default #1 Thu Aug 24 09:51:41 UTC 2006 (from uname -a)
On the linux system where my program should run, it segmentation faults before executing even the very first instruction ("Trace ?r" at the moment).
When the program was smaller I could work around the segmentation faults by adding extra "Say" statements.
The identical program (less the "Trace ?r") runs without error under IBM Object Rexx on my Windows XP system.
