Experimental Physics and Industrial Control System

Hello
I am writing a driver to control a custom power supply using asynPortDriver, I am using asynOctetSyncIO->writeRead interface to do IO with the controller but the IOC crashes on calling the function (https://github.com/AbdallaDalleh/psc-asyn-driver/blob/main/pscApp/src/PSController.cpp#L83
). The asynOctetSyncIO interface crashes specifically on line 238, when casting the userPvt pointer of the passed asynUser pointer. I used this interface many times before and I have no idea why the segmentation fault happens.
Best Regards,
Abdalla.
