So I think the problem is the CHECK_FONT in 

DEFUN ("font-xlfd-name", Ffont_xlfd_name, Sfont_xlfd_name, 1, 2, 0,
       doc: /*  Return XLFD name of FONT.
FONT is a font-spec, font-entity, or font-object.
If the name is too long for XLFD (maximum 255 chars), return nil.
If the 2nd optional arg FOLD-WILDCARDS is non-nil,
the consecutive wildcards are folded to one.  */)
     (font, fold_wildcards)
     Lisp_Object font, fold_wildcards;
{
  char name[256];
  int pixel_size = 0;

  CHECK_FONT (font);
...



(gdb) up
#12 0x0017b190 in Ffont_xlfd_name (font=3724841, fold_wildcards=3688449)
    at /vol/freeware/cvs/emacs/head/emacs/src/font.c:4115
(gdb) p font
$7 = 3724841

Maybe this already helps. If not I need a few hints how to proceed.
font-xlfd-name seems to be a new function.
