Comment(by cgohlke):

 Could be that msvc9 compiled code for amd64 executed rk_chisquare() before
 rk_noncentral_chisquare(), unlike code compiled by other compilers. In
 that case the following should work reliable (not tested):

 double rk_noncentral_f(rk_state *state, double dfnum, double dfden, double
 nonc)
 {
     double t = rk_noncentral_chisquare(state, dfnum, nonc) * dfden;
     return t / (rk_chisquare(state, dfden) * dfnum);
 }
