Fix Build Warnings for AArch64 (#2242)

This commit links to issue (#2234).

When cross-compiling for AArch64, using gcc 13.3, you encounter three
warnings types that turn into errors:

- maybe-uninitialized
- stringop-truncation
- strict-aliasing

This commit fixes all the warnings found, in regards to the first two
rules. To resolve the warnigns due to strict-aliasing, I am editing the
CMake build system.
