PJ31255: TPF TOOLKIT DOES NOT STOP AT CTL DUMP FOR INVESTIGATION
Closed as program error.
If an operational dump is generated (SERRC_RETURN or SERRC_EXIT) by an application then the Toolkit 1) Displays message 'execution may have stopped between statements' 2) Displays popup 'the following exception has occurred' ...... Select which action to take etc etc 3a) If we select the default 'Step exception handler' then the next source line is displayed provided the exception is SERRC_RETURN. 3b) If the operational dump is SERRC_EXIT then if the option 'retry exeception' is selected then the user can examine the situation to ascertain the cause of the exception. If a control dump is generated by an application then the Toolkit 1) Displays message 'application terminated' This means that if a control dump occurs then the application A) May not be aware that it has occured. B) Cannot examine the situation to ascertain why the control dump occurred.

(That is, real time segments that are not marked as NODBUG).
SOLUTION: With PJ31255 applied, Debug on System Error will trap all ECB-related system errors. For dumps that occur outside of a real-time segment, the debugger will stop at the instruction causing the error so the user may investigate the dump. Following this however the dump will still be taken in the ECB when the user resumes execution, regardless of any changes the user might make while the debugger is stopped. For all dumps that occur within real-time debuggable code the behavior will remain as before.
