That's not the only blunder.

  Block = RECORD

presumably should be

  Block = POINTER TO RECORD

If either error had occurred in isolation the resulting effect would not
have been as catastrophic.

Interestingly the original Oberon compiler which the BlackBox compiler was
derived from reports the error/s without crashing. That indicates to me that
the compiler's inability to gracefully handle this particular combination of
errors is related to the modifications done to allow for the enhanced
RECORD-related features of Component Pascal.
