CVI aborts with no warning when compiling

Question

When I compile a simple instrument driver with the CTRL-K shortcut in CVI 2009 (9.1) it aborts CVI without warning
No popup, no nothing.
All I had done was delete a typedef in the driver file for a structure containing GPIB configuration info.
After it did it about 5 times in a row it finally stopped when I included a header file that re-established the typedef for the GPIB struct.
So the problem was that this typdef appeared as a parameter type in a prototype in another header file, and when I eliminated the definition it caused the abort. The abort was immediate, I have to think it was something wrong in the preprocessor.  I do not have precompiled headers checked in the build options.  I am using the standard CVI compiler. 
Weird, huh.

Some how I knew you'd ask for that
I don't have a simple case. 
It was absolutley repeatable, I couldn't believe it when it first happened.
I had something like this in the driver file:
typedef struct _GPIBConfig {
  DWORDBus;
} GPIBCONFIG, * LPGPIBCONFIG;
and in a header file I had a prototype that used the typedef as a parameter type:
headerfile.h
INT myFunc (GPIBCONFIG config);
When I eliminated the typedef  from the driver file, I got the crash.
When I added another header that defined the GPIBCONFIG struct, the crashes stopped.
Restarting CVI did not cure the problem.  When I restarted, CVI did a popup saying the previous instance of CVI had been stopped abnormally.   I recovered the project per the popup.  Then when I restarted and recompiled, it crashed again, but when I restarted I didn't get the popup.
