I can not assure it. But I recall something similar happening to me, also 
with a Alpha EV7, and, if I can remember correctly, it was related to the 
IEEE floating-point arithmetic (see the related chapter in the gsl 


#include <gsl/gsl_ieee_utils.h>

to the code solved the problem. This if I am  not mixing up things here, 
which of course could be, knowing myself, ahemm ;-)
