SafeIntLib is only safe if it is used correctly, and if it signals an overflow, the error must be handled, rather than limping on and using garbage data from the stack, as this may turn out to be more dangerous than using the overflowed value. So initialize RelocBase and RelocBaseEnd to NULL first, as it will get tested even in case of overflow, and this will prevent it from being initialized as expected.
