That's what I wanted to know.  The code around line 1258 is
this:

1255  val = AREF (font, FONT_FOUNDRY_INDEX);
1256  if (! NILP (val))
1257    /* ":foundry=NAME" */
1258    len += 9 + SBYTES (SYMBOL_NAME (val));

So the variable `val' is suspicious.  Please check the type
and value of `val' as this:

(gdb) p val
(gdb) xtype
(gdb) pp val
