| Subject: | Phoebus on Windows host causes IOC crash on WSL |

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!
