bug#4170: 23.1.50; Crash with fontset-font


From: YAMAMOTO Mitsuharu
Subject: bug#4170: 23.1.50; Crash with fontset-font
Date: Mon, 17 Aug 2009 16:42:01 +0900
User-agent: Wanderlust/2.14.0 (Africa) SEMI/1.14.6 (Maruoka) FLIM/1.14.8 (Shij┼Ź) APEL/10.6 Emacs/22.3 (sparc-sun-solaris2.8) MULE/5.0 (SAKAKI)

Steps to reproduce:

  1. emacs -Q
  2. evaluate (set-fontset-font nil #xa0 nil) and (fontset-font nil #xa0)

Then Emacs crashes.

With -DENABLE_CHECKING, I got the following assertion failure:

.../src/fontset.c:2118: Emacs fatal error: assertion failed: VECTORLIKEP((val))

2113              for (j = 0; j < ASIZE (elt); j++)
2114                {
2115                  Lisp_Object family, registry;
2116    
2117                  val = AREF (elt, j);
2118                  repertory = AREF (val, 1);
2119                  if (INTEGERP (repertory))
2120                    {
2121                      struct charset *charset = CHARSET_FROM_ID (XINT 
(repertory));
2122
