The previous fix in r652 was _almost_ right. There was still a one word (4-byte) overlap between _irq_stack_top and the start of the data segment. _irq_stack_end + _irq_stack_size leaves the '.' pointer at the word immediatly after the stack. This commit corrects this error and places _irq_stack_top on the last word _inside_ the reserved space for the irq stack.
