First, the "lisp quits" problem: That error comes from Freeglut, and I 
think it does an exit which Lisp cannot intercept. If this becomes a 
problem, we will have to talk to the FG people about changing that, or 
just fork FreeGlut.

As for the font, that translates to glut_bitmap_8_by_13. But I see it is 
the first font attempted by the lesson-14 demo, so I do not know whether 
it is just a problem with that font on that version of Freeglut or 
whether none of the fonts will work. You might try put 
GLUT_BITMAP_HELVETICA_12 first. Or really track the problem down: look 
for a definition of  fgFontFixed8x13 in freeglut_font_data.c Should be 
there and look like this:

  const SFG_Font fgFontFixed8x13 = { 
"-misc-fixed-medium-r-normal--13-120-75-75-C-80-iso8859-1", 93, 13, 
Fixed8x13_Character_Map, -1.0f, 2.0f };
