In another email you write:

"A simple case as shown bellow does NOT fail, but a more complex example with 
30+ tasks, 40+ timers etc does seem to reproducibly fail."

I need a self contained test case that reproduces the problem to help you.

Ok, if you end up here with the following task


rtems_task test_wake_after(rtems_task_argument ignored)
{
     for(;;)
     {
         rtems_task_wake_after(10);

         /* application code happening on interval here */
     }
}

then the system is broken.  This can be a general memory corruption (heap, 
stack, global variables) or a bug in the exception processing.
