Delphi 2009 Exception Tracking

Delphi 2009 Exception Tracking

I've inherited a big @$$ Delphi Application that by itself are so full of
problems, that I'm not sure how I will be able to track down a problem
that I'm currently getting.
The application crashes and terminates abnormally, and I'm unable to
establish a pattern. I've added madExcept, and that helped me a lot
getting some other problems, but when the application dies, not even
madExcept is able to stop it so that I can get an exception report. I've
downloaded Eurekalog as well to see if this can help me, but no luck.
Does anybody have a solution on what I can try. Any tool that will be able
to help me out in tracking down the problem. SmartInspect does have some
kind of solution, but I will have to change a lot of code for it to work,
and unfortunately the main unit of this application sit with over 53k
lines of code. (Just nasty).
Any help on what I can use to track this error will be appreciated. I need
to but this "tracker" on a user machine because this application is
running live at almost 2000 users.
If anybody also know why a random RICHEDIT20.DLL access violation will pop
up now and again, it will be very usefull, because why it happens just
baffles me completely.
Thanks Jaques
