I expected that the same optimalization (-O2) gives the same results in 64-bit machine as in the 32-bit case.
No! the architecture is different, and actually compilers are different (at least, might contain different bugs :) ).
:If the only way of solution is to hardcode the constants into the code, are the correct values known?
Sure, they are known. And they should be listed somewhere...
But as a hot fix (we are working on a solution for this issue) - I can recommend you a simple trick. Optimize the code with -O0, and print these values.. After that - simply hardcode them..
Best,
