This is typical for a hard crash of Creo.
What are the conditions in which you encounter this error... and is this true in all cases or just a particular operation of file-set? If it can be traced and duplicated, then customer support might be able to isolate the problem.
PTC takes hard crashes very seriously but they need your help. You have to report a support case. If you are an active maintenance customer, you have the ability to create support cases.
I have has sessions that cause hard crashes such as this and I have had corrupted files that cause hard crashes. The Traceback log is of little use to PTC. They need a lot more information to get to the root of the problem.
