hello,

I am using the QP solver in 3D to solve many many little linear programs.
I am using CGAL::Gmpzf ET as exact number type and 
Exact_predicates_inexact_constructions_kernel as kernel.

I encounter the following assertion when solving:
CGAL_assertion(CGAL_NTS is_finite(d) && is_valid(d));

into

 Gmpzf( double d)
 {
   Protect_FPU_rounding<> P(CGAL_FE_TONEAREST);
   if (d == 0) {
     mpz_init (man());
     e = 0;
     return;
   }
   static int p = std::numeric_limits<double>::digits;
   CGAL_assertion(CGAL_NTS is_finite(d) && is_valid(d));


I have checked and all linear constraints are not degenerate, etc.

Any hint about where this could come from?

Any help would be much appreciate,

Pierre
