Strange problem with EPICS areaDetector

Hi Folks,

I encountered a strange problem with EPICS 7.0.8 under Ubuntu 22.04 on x86_64. My IOC crashes when loading ADBase.template:

>dbLoadRecords("/home/srsi2d/EPICS/EPICS-7.0.8/modules/src/areaDetector/ADCore/db/ADBase.template", "P=WIZZLERHD:HZDR:,R=asicam3:,PORT=ASICAM3,ADDR=0,TIMEOUT=1")
>epicsMutex pthread_mutex_unlock epicsMutexOsdUnlock failed: ERROR Operation not permitted
>epicsMutex pthread_mutex_unlock epicsMutexOsdUnlock failed: ERROR Operation not permitted
>*** buffer overflow detected ***: terminated

The gdb backtrace shows the following:

If I comment out the calcout record it crashes at the next busy record. So it seems that my base installation has a problem, but why and what?
The ai, ao, bi, bo and stringin records seem to work fine. The calcout and busy records are defined in my apps dbd file.

Any idea what could be wrong?
