Generated DLL using Matlab's real-time workshop. Using LabVIEW5, CIN could use the generated DLL. When switching to LabVIEW 6, the program crashes.

Hello, I made a DLL using Matlab's real time workshop. Using Labview 5, it was possible to use this DLL by means of the CIN block. Now I use Labview 6i, the same DLL as before gives an error, resulting in crashing Labview. The exact error reads: "File I/O: LabVIEW.exe - Application Error, The instruction at "0x02e01ec9" referenced memory at "0x00000000". The memory could not be "read"." Please advice.

Make sure you aren't passing in any empty arrays into your dll. I am pretty sure it allowed you to do this in LabVIEW 5 but it will now cause a crash in LabVIEW 6.

Yes, it's true, an empty array causes the crash. Initialization of the array by using an 'initialize array' block won't solve the problem either.
