Hello,

I tried to compile cgal 5.1 with emscripten and boost 1_62.

I had to bypass a piece of code in Interval_nt.h 

#if 0

       CGAL_assertion_msg(-CGAL_IA_MUL(-1.1, 10.1) != CGAL_IA_MUL(1.1, 10.1),

                          "Wrong rounding: did you forget the  -frounding-math  option if you use GCC (or  -fp-model strict  for Intel)?");

       CGAL_assertion_msg(-CGAL_IA_DIV(-1., 10) != CGAL_IA_DIV(1., 10),

                          "Wrong rounding: did you forget the  -frounding-math  option if you use GCC (or  -fp-model strict  for Intel)?");

#endif   

and use boost 1_62 to get a correct compilation.

Many example work, but the corefine example crash on one  CGAL_triangulation_assertion( s != LEFT_TURN ); 

CGAL-5.1/include/CGAL/Triangulation_2.h at line 928

This is the code where crash happen

Vertex_circulator start = incident_vertices(infinite_vertex());

    Vertex_circulator pc(start);

    Vertex_circulator qc(start); ++qc;

    Vertex_circulator rc(start); ++rc; ++rc;

    do {

      Orientation s = orientation(pc->point(),

                                  qc->point(),

                                  rc->point());

      CGAL_triangulation_assertion( s != LEFT_TURN );

      result = result && ( s != LEFT_TURN );

      ++pc ; ++qc ; ++rc;

    } while(pc != start);

does anyone have any idea how to fix this problem?

Thanks in advance.
