Hello Martin,
Your attachment (IOC_customization.diff) has "motorR6-8" in it.
It that the version of motor module you are using; R6-8?
If not, what version of the motor module are you using?

Hi Matthew,
I'm not too sure, but you might be trying to use non-asyn motor
device support with an asyn based driver.
drvAsynMotorConfigure configures the Asyn motorSim driver. So the
motor record needs to specify DTYP as asynMotor.
Hmm, you might be right about that. To clean things up I started with
a fresh IOC and tried to followed the example from
motorApp/MotorSimSrc. See the attached file for my configuration.
Unfortunately the problem still occurs. There are no error messages on
the IOC console before the IOC crashes. I also managed to get some
more debugging symbols:
