What means "a crashed program" ? Does this also include Ada exceptions
or only "hard" crashes (illegal pointer reference)that are recognized by

What I want do is, give the (tested) application to the end user, and
react only if he reports an error. I think the user don't accept to run
the app within a debugger.

Do you get symbolic values for (procedure) local and global variables ?

Do you know whether there is a way under Winxx ?
