Are you trying to communicate with such an external program?

Can you narrow down the error to a specific portion of your code?

Or is the crash happening inside the external software? If so, you should look for assistance from its producer.

I can give you 2 suggestions as to how to address this kind of problems

1. Add proper error checking to all I/O functions and carefully handle every abnormal return code you get
2. Dig into System Event registry searching for errors related to your application or the 3rd party software: normally the error logs include some informations that may help you discriminating the location of errors
