SQL-error "-602-POS(1) System error: Move error" in DDL statement

Hi DB experts,

during a "harmless looking" SUM operation with MaxDB 7.9.8.34

ALTER TABLE "DAAG_PTO" modify ("PARTITIONING_OBJECT" VARCHAR2 (000030))

we got a

SQL-error "-602-POS(1) System error: Move error" in DDL statement for "DAAG_PTO "

In Kernel log we have:

20011:  Bad parameter: source size [8192] dest size [8192], source addr [0x7fc40ad6b048]+1, dest addr [0x7fc49214f000]+81, -515 bytes to copy; module vbd37+noPIC.cpp, pos 584,_FILE=vbd37+noPIC.cpp,_LINE=584

There where some PTS fixed in lower releases but it seems not in DDL context.

Anybody fixed this already ?

Thanks in advance,
