Throwing in my CAD 0.02...
I have had working apps terminate abnormally when it finds control characters in the data itself. Eg EOF markers.
This was usually the result of corrupted data. I have also expereinced this when there was corruption in the header itself.
What has worked for me is to try similar data from another source to determine if the data is the problem, and if it is, inspect and clean it.

>At this point, I am not trying to create an exe; I am using a very simple program which contains only that code where the problem occurs. In the exe of the main app, where there is a read, the problem is much more complex as the exe just shuts down without any error or warning.
