  • RULE-11-4 - ConversionBetweenPointerToObjectAndIntegerType.ql:
    • Fixed issue #331 - consider 0 a null pointer constant.
    • Improve reporting of the order of the cast and the actual types involved.
    • Improve reporting where the result is expanded from a macro by either reporting the macro itself (if it is not dependent on the context) or by including a link to the macro in the alert message.
  • RULE-11-5 - ConversionFromPointerToVoidIntoPointerToObject.ql:
    • Fixed issue #331 - consider 0 a null pointer constant.
  • RULE-11-6 - CastBetweenPointerToVoidAndArithmeticType.ql:
    • Fixed issue #331 - accept integer constant expressions with value 0 instead of null pointer constants.
