Pointer corruption on Windows

["Koennecke Mark \(PSI\) via Tech-talk" <tech-talk@aps.anl.gov>]

Hi,

I am trying to write a motor record driver for the PXI7344 motor controller from

National Instruments and I am experiencing a weird pointer corruption problem. 

First the environment:

- Windows 10, PSI computer security wants that

- MS Visual Studio 2010, I have to interface with the NI FlexMotion library which is EOL and from 

  this time

- base-3-14-12

- asyn4-25

- motorR6-9

I am using the asynMotorController. What I see in my debugger is that everything is fine with my 

pointer until epicsEventSignal(pollEventId_) is called in asynMotorController::wakeupPoller().

After that call my this pointer is corrupted and everything goes downhill from then. I tried to 

override wakeupPoller() to an empty method in order to get more information but then 

I get the pointer corruption on the call to  epicsEventWaitWithTimeout(pollEventId_, timeout) in 

asynMotorController::asynMotorPoller() 

Any ideas what could be wrong here? 

Best Regards,
