Then i did a "man crash", the crash home page was mentioned in the last section. I went into the site and downloaded the latest crash mentioned there.

------- Comment From sripathik.com 2009-06-29 09:14 EDT------- To RH: We have closed this bug on IBM bugzilla. We have documented the problem with crash that ships with RHEL5.2.
