ncWaitForState() function causes a General Protection fault in labWindows/CVI 8.1

Look at the very first message:

CAN 2.6.3 using a NI PXI-8512/2 .

labWindows/CVI 8.1.1 (361)

Dennisatwork,

Ah, Sorry about that, I remember seeing the 8512 now. Since I can't reproduce the error you are seeing on my machine as is, I am going to try this code on a machine with CVI 8.1 as soon as I get a chance to see if I can narrow down the issue to a specific component of your set-up.
