There is an Ada task attribute for stack size.  From 
http://www.adahome.com/FAQ/programming.html:

3.7: How do I increase the stack size for a task? 

Define the task as a "task type" and then use a pragma representation clause. 

     task type A_Task_Type;
     for A_Task_Type'STORAGE_SIZE use 10_000;
     -- 10K bytes allocated to instances of A_Task_Type
     A_Task : A_Task_Type;

But it does make me ask if you are doing something brutal on the stack.
GNAT/RTEMS should be using quite large stacks for Ada tasks by default.
