Yes I have seen this error message from time to time when the Ada program
causes a signal (sigill,sigbus) and so on. I have no experience with  
VADS ADA 6.2.3 , but we have been using SunAda 2.1.1 which is a VADS 6.2 
something sold by Sun. I found that this error only exist when you run
on an UltraSparc platform, running the same program on older sparcs (5/10/20)
gives your exception handler the control.

However running the program in the debugger normally gives you a clue about
what is causing the error.
