The program seems defined for usual ILP32 architectures. It seems
you will have to investigate.

After determining which global causes the difference in checksums (let's assume it's int G),
I like to replace in the program the regexp: /[*] block id: \([0-9]*\) [*]/
by: printf("block: %u, G: %d\n", \1, G);

Usually, if you are lucky, this does not perturb compilation enough to hide the bug,
and it suffices to determine where the execution traces diverge and/or where
G gets a different value.
