Crash on SystemState and BRMShmImpl after Update to 1.09

Hello,

we are facing a lot of prblems because of DBRM errors with a columunstore made on 1.07. After teh current update from 1.07 over 1.08 (start an stop with no issue, incl. boost 1.57 installation) to 1.09 the system was available and good to answer some querries. AS weel creating a table. With import from exiting table (cpimport) the system crashed in the same manner as version 1.07 before.
We also tried some change sin the cilunstore.xml and clearShm, load/save_brm option but nothing does help.

Part of the log:
