I am a novice programmer wondering why the "terrain" demo has problems when 
the
"input" and "kernel" demos run without issue, and what needs to be done to fix
the problem.

I'm using g++ compiler (codelite IDE), GNU gdb debugger, geomview 1.9.4 and
CGAL 3.3.1

it builds and runs until it hits line 86 of terrain.cpp. 
Geomview closes and the error message is: 
"Error <1>: OOGLNew: couldn't allocate -16 bytes: SKEL lines: Cannot allocate
memory
File: mallocp.c, line62"

The operation in line 86 is
...
81  // use different colors, and put a few sleeps/clear.
82 
83   gv << CGAL::BLUE;
84   std::cout << "Drawing 2D Delaunay triangulation in wired mode.\n";
85   gv.set_wired(true);
86   gv << D;
...

stepping into that line shows the problem appears in line 109 of
/usr/include/CGAL/IO/Triangulation_geomview_ostream_2.h

...
96   template < class GT, class TDS >
97   Geomview_stream&
98   operator<<( Geomview_stream &gv, const Triangulation_2<GT,TDS> &T)
99   {
100     bool ascii_bak = gv.get_ascii_mode();
101    bool raw_bak = gv.set_raw(true);
102
103    if (gv.get_wired())
104     show_triangulation_edges(gv, T);
105    else
106     show_triangulation_faces(gv, T);
107
108    // Footer.
109    gv << "}})";
110
111    gv.set_raw(raw_bak);
112    gv.set_ascii_mode(ascii_bak);
113    return gv;
}
