Thanks for the info. It makes sense now. So this is similar to the Intel x86 processor with respect to short and long jumps. And the problem is not within our code but between our code and the OS code that the distance could be beyond 16MB? It is still strange that I am imagining between our code and the OS/library code, it should only have CALLs instead of BRANCH instructions but then I am not familiar with PPC. Untill CALLs can also have 24-bit limitations. I am surprise that not more people hit this. We must be the lucky ones that the loader decided to load a lot higher than other people.

Thanks again for the explanation.
