Summary: tktest segfaults with Xft

Initial Comment:
Hello!

I built tk-8.5a6 on Solaris-10 (with Xft enabled). My DISPLAY is set to the Linux desktop.

In addition to a large number of test failures, tktest simply crashes. It happens right after it reports the failure of test font-17.5, so it must be in font-17.6.

The crash is in tkUnixRFont.c:186:

  184   
  185       if (XftPatternGetString(ftFont->pattern, XFT_FAMILY, 0,
  186               &family) != XftResultMatch) {
  187           family = "Unknown";
  188       }

The immediate cause of the crash is ftFont being NULL. The stack is:

=>[1] InitFont(tkwin = 0x2ed68, pattern = 0xe96da8, fontPtr = 0xbfc930), line 186 in "tkUnixRFont.c"
  [2] TkpGetFontFromAttributes(tkFontPtr = (nil), tkwin = 0x2ed68, faPtr = 0xffbfa3c0), line 362 in "tkUnixRFont.c"
  [3] Tk_AllocFontFromObj(interp = 0x30958, tkwin = 0x2ed68, objPtr = 0xb680c0), line 1164 in "tkFont.c"
  [4] Tk_FontObjCmd(clientData = 0x2ed68, interp = 0x30958, objc = 4, objv = 0xffbfa8d8), line 590 in "tkFont.c"
  [5] TclEvalObjvInternal(0x30958, 0x4, 0xffbfa8d8, 0xbfad3c, 0x2a, 0xe8a31), at 0xfeeb0264 
  [6] TclEvalEx(0x30958, 0xc, 0xbfad66, 0xbfad5e, 0x2, 0xd), at 0xfeeb1594 
  [7] TclSubstTokens(0x30958, 0xffbfaaf8, 0x1, 0x0, 0x2, 0x14000), at 0xfef5819c 
  [8] TclEvalEx(0x30958, 0xbfad3b, 0x3, 0xbfad3a, 0x2, 0x1), at 0xfeeb10e0

Please, advise.

Before you ask, yes, reconfiguring with ``--disable-xft'' works around the
problem.
