Hi Heinz,

> NDArray::release: WARNING, no owner

That message means that NDArray.pNDArrayPool is 0.  That could be a memory corruption problem.  What leads you to think that it might be a mutex problem?

Subject: Running area detector simulator IOC on OS X aarch64 (M2) , segmentation fault

Hello,
I am trying to test on a new MAC with M2 processor areadetector.
I was able to build it and start a simulator IOC. But when I start the simulator camera I get a segmentation fault. I haven't searched further for the error and wanted to ask here first if someone has alrerady  seen this (and maybe solved it).

epics> dbpf 13SIM1:cam1:Acquire 1
NDArray::release: WARNING, no owner
DBF_STRING:         "Acquire"
./start_epics: line 2: 31835 Segmentation fault: 11  ../../bin/darwin-aarch64/simDetectorApp st.cmd.darwin

I guess it has something to do with Apple's lack of (limited) support for POSIX mutexes?

Danke Heinz
