Failure occurs on the following line:
  
    aProjDB.Create( f, dbMode , REALinsightApp.kValentinaSegmentSize )

where f is non-nil, read/write not locked, exists
dbMode = 1
segmentSize = 32 * 1024

No crash log, no report, no exception... just sudden death.

Any suggestions of what checks, tests, etc I should/could perform?

I guess worst case I could keep a separate global file that all my apps
check to see which database files they have open for use.
