Hi,
I'm trying to simulate a motor with motorSimSupport but my IOC crashes
as soon as the record is processed (e.g. by issuing caput test:motor1
42). Motor support for my Parker hardware motor works fine. Here is what
I have:

g6test2App/Db/Makefile:
g6test2_DBD += asyn.dbd
g6test2_DBD += drvAsynIPPort.dbd
g6test2_LIBS += asyn

g6test2_DBD += motorSupport.dbd
g6test2_DBD += devPC6K.dbd
g6test2_DBD += motorSoftMotor.dbd
g6test2_DBD += motorRecord.dbd
g6test2_DBD += motorSimSupport.dbd

g6test2_LIBS += Parker
g6test2_LIBS += softMotor
g6test2_LIBS += motorSimSupport
g6test2_LIBS += motor

Here is the record:
record(motor, test:motorRad) {
  field(DTYP, "Motor Simulation")
  field(OUT, "test:posRad PP MS")
}

In st.cmd I have:
motorSimCreate( 0, 0, -32000, 32000, 0, 1, 1 )
drvAsynMotorConfigure("motorSim1", "motorSim", 0, 1)

Here is a backtrace:

Any ideas?
