However, we also copy + the save area located at the stack pointer of setjmp's caller. + This save area will typically remain intact until the longjmp call. + The one exception is when there is an intervening alloca in + setjmp's caller. This is certainly an unusual situation and is + likely to cause problems in any case (the storage allocated on the + stack cannot be safely accessed following the longjmp). As bad as + it is, on most systems this situation would not necessarily lead to + a catastrophic failure. If we did not preserve the extra save area + on Xtensa, however, it would. When setjmp's caller returns after a + longjmp, there will be a window underflow; an invalid return + address or stack pointer in the save area will almost certainly + lead to a crash. Keeping a copy of the extra save area in the + jmp_buf avoids this with only a small additional cost.
