General limitations:
- Watch expression: Agents are not supported (for instance "agent my_function" is not supported").
- The debugger is still not very helpful when the execution is stopped inside an invariant.
Limitations or known bugs for the Classic debugger:
- Evaluating Precursor will produce the current feature's Result (not the precursor)
- If you use any of the previous non supported expressions in a breakpoint condition, since the evaluation is failing the condition will always return True. In such case the debugger will stop.
Limitations or known bugs for the .Net debugger:
- It happens the debugger does not show the correct executed line, especially when dealing with disabled assertions or disabled debug clauses.
- The same trouble occurs when stepping through an unordered inspect code.
Various known issues for classic system :
- If a precondition is violated inside a rescue, the debugger reports the assertion violation will the exception's tag.
- If you use the "Disable Assertion Handling" functionality when the execution is stopped in a rescue, the effect might be cancelled as soon as the execution exits the rescue's associated feature.
