Crash in FOR loop #65

Closed skx closed 6 years ago

skx commented 6 years ago

An overnight run of the fuzzing-tool found the following program, which crashes:

  LET term=0
  FOR I=0TO term STEP

(There were 1000+ crashes found overnight; half of them were invalid DATA statements, the other half were hangs, due to INPUT or endless loops, be they GOTO/GOSUB/FOR. Yay!)
