Are you certain that it necessarily will converge? Are you getting the
same random sequence from the two compilers?

What have you done to try to characterize the nonconvergence? Do you
even have the slightest idea where the two compilers are diverging? I
would strongly recommend that you study that, using write statements or
a debugger.
