The import (testcase) I built on RHEL 5.5 crashes on RHEL 5.5, but if I ran it on Fedora 19, it works. So if you take the import you built on CentOS 5.8 (crashes on CentOS 5.8) to the Fedora 17 system, I think it will run fine. May be the above information will give you some hint regarding what's the cause of this issue? Thanks, Tammy
