- "Compiler error" undoubtedly means that there is an internal error being
- detected within the compiler on itself. This is not a user-generated
- error. Report this to your support people as a defect in the compile
- path.
-
- Each piece of the compile path has internal integrity checks on its own
- data structures to warn you that it's possible that the compiler made a
- mistake somewhere. When one is detected it prints out a message like
- the one you see. The fact that the error is reported at the end of a
- program unit doesn't mean that the error occurred there; rather, it
- means that final validity checks for the program unit were made once all
- input had been seen and one of these checks detected a problem.
