Hi Hinko,
Since it generated a core file you should be able to do some more debugging with gdb. For example what are the values of "size" and pMsg->postsize in caserverio.c? You might be able to figure out what PV this is.
Mark

Dear EPICS users,
here is the error I got from the IOC running EPICS base 3.15.4:
