Are you really sure that you are not getting the exception. Add a when
others exception handler to your
task that does a text IO.. If you have no exception handler and you get an
exception in the task, the task
will silently terminate. If you get one in "the procedure" (e.g. main
program in a program with no tasks) the program
will terminate and print the exception..
