Subject: 23.1.50; Crash with fontset-font
Date: Mon, 17 Aug 2009 16:42:01 +0900

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

Thank you for the report.  I've just installed a fix.

By the way, should I install the same fix for EMACS_23_1
branch?
