Watch out for exception handling

HCL Notes/Domino 8.5 Forum (includes Notes Traveler)

Subject:

We are able to gracefully support shutting down our 8.5.1 64 extension managers. In your case, you might take a hint from the back trace line that suggests a C exception handler was invoked.

We wrestled with exception handling a lot since the 64 bit compilation required us to use a very modern MSVC compiler that had changed the default settings for SEH (Structured Event Handling) -- we had to explicitly set /EHa.

C++ runtime parameter checking is on by default in newer MSVC dlls so we also had to set a flag to ensure that iterator problems would throw a catchable exception instead of crashing. (Our Extension Manager is written in C++). In this case, we wouldn't get any NSDs ... the Domino process just died and left an entry in the Application event log.

If you have solved this problem or learned more about its nature I'd be interested to hear about it.

Ken Gartner/Permessa.
