-Tip: If this handling is not done correctly, a typical symptom is that global variables "don't work", i.e. reading from them doesn't yield the right value, and writing to them doesn't persist. A good way to double check this is by using a debugging a dumping memory at runtime and checking if it matches the virtual memory layout of the ELF file.
