Phoebus on Windows host causes IOC crash on WSL

[Zhibang Shen via Tech-talk <tech-talk at aps.anl.gov>]

Hi,

I would like to build the motorMotorSim module in my WSL, Ubuntu 24.04 LTS. And I have succeeded building the module, ran it and accessed the PVs from the host of Windows with caput,caget,camonitor...

But there is a wired thing that if I want to use Phoebus to access the PVs, the IOC will crash.

The Phoebus also runs on the Windows host.

motorMotorSim IOC on Ubuntu(WSL) --> successfully run

caget.exe/caput.exe on Windows(host) --> successfully access the PVs

Phoebus on Windows(host) --> cause the IOC crash

For example, if I run the motorall_x.bob in execution mode, the IOC will show such information:

epics> *** buffer overflow detected ***: terminated

Aborted (core dumped)

I have found there was a talk from 2010 saying that this could be an issue caused by the OS itself. I am not sure if WSL is related to this issue.

Could any one help with this? Thank you!
