I don't know what GNAT does in this case, it may even have a bug. But
the code in your example should cause the exception to be propagated to
the caller, then silently terminate the task. I can well imagine
situations where this would cause a program to hang. (If some tasks in
a process, but not all tasks are terminated, the program unit the tasks
depend on will not be left. I think that is what you mean when talking
about zombies.
