I started to rewrite the code of this patch because it is much too sensible to the way the compiler aligns its data structures. I didn't try it on Linux but I tried it with several optimize options (gcc) on Solaris and it proves that incrementing pointers in structs is not reliable. I started rewriting the code with two dedicated serialize & unserialize functions for each data structure, but I didn't have enough time to complete it, and I won't be available to work on it until the end of August.
