--- Comment #13 from Tammy Hsu <tammy at Cadence dot COM> ---
Hi Mikael,

My last comment probably is not clear enough. 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
