I doubt it. You first need to demonstrate that it is in fact a compiler
problem rather than an ill-expressed algorithm.
If the application does not take too long to run, I suggest you use the
compiler switches to turn off all optimisation and turn on all checking.
This could indicate a problem with your code or possibly with the compilers.
If the results are unchanged from your present ones then you may have an
interesting case !
