void someFunc()
{
int stackInt = 4;
someOtherFunc(&stackInt);
}
Is it the case that stackInt's address space could be reallocated after someFunc ends, making it unsafe to assume that the value passed to someOtherFunc represents the stackInt variable with value 4 that was passed to it? In other words, should I avoid passing stack variables around by address and expecting them to still be alive after the function they were initialised in has ended?
