[Help-gsl] gsl_histogram_get_range

[Emiliano Olivieri]

Ok, if I use in my program the following, everithings works fine!

double lower,upper;
gsl_histogram_get_range (h,gsl_histogram_max_bin (h),&lower,&upper);


In this other case, my programs stop with the message: "Bus error"

double *lower,*upper;
gsl_histogram_get_range (h,gsl_histogram_max_bin (h),lower,upper);


WHY? I got crazy, is it some kind of bug or am I wrong with something?
I tested on two sistem, G3 and G4, with 10.4 and 10.3 system rispectively...

HELP!
