I can see three possible reasons but I cannot be sure if you don't
post your entire program.
Possible cause 1: exception during elaboration, i.e. before your main
subprogram starts.
Possible cause 2: exception during elaboration of the main
subprogram's local variables, i.e. before its "begin" keyword.
Possible cause 3: exception in a task other than the environment task.
The stack trace points you to the exact location of the problem.
