Note that generate_tests.c was updated to special case the operands for these tests. 32-bit gcc inserts a helper function into the compiled binary to perform 64-bit mod and div operations. This helper has some optimizations that shortcut the calculations in some cases. Using specific (large) values bypasses those optimizations which results in taint labels begin transferred to all bytes in the destination variable.
