Jack, are you using Fast Bounce for your Export?

If so, try a real time bounce and see if it works

I don't think fast bounce has anything to do with it as it will work if I open a project, import then export, close the project and then open a new project and repeat the import/export.  Its only after "x" number of import/exports to the same project track. 

Its a deep (in the program) seated problem and as I mentioned something no one probably even dreamed someone would do, thus it was never run through program checkout.  I'm probably the only one in the world that tried to do this procedure.

It has nothing to do with the recording interface unit.  It does it with either my Roland Octa-Capture or MAudio Fastrack Ultra 8R connected (they connect to different USB ports on the PC).

Edit/Added:  Maybe the upcoming X2a will inadvertently fix this.

Thanks for sending in the bug report. This issue has been fixed. The crash actually only occurs if you happen to explicitly or implicitly select a silent area on the track before export, which is why you don't typically run into this issue.

Great.  Is this fix going to be part of X2a?  or a separate patch?

This is something that would rarely happen, just that in the application I used it did show up.   All my "completed" songs have 2 seconds of silence at the beginning.  That is why the silent area issue.

Thanks/Jack
