----- Question -----
_stack_end looks good (0x20000000 + 0x42000) [264 × 1024 = 0x42000]
_stack_start looks good (0x20042000 - 0x400) [1 × 1024 = 0x400]
_stack_size, based on the math above, should be 0x400. The math for the other two values (_stack-end - _stack_size) is correct, but the value for _stack_size makes no sense to me. Am I misunderstanding what objdump is trying to tell me?
