Sooner than planned: here's the "solution" (sort-of)

Just failed to reproduce both the crash and the valgrind error message.
The problem doesn't occur any more. What I did:

  - *NOT* upgrade the gcc compiler
  - upgrade freetype2 to CVS/HEAD again
  - upgrade valgrind to CVS/HEAD again
  - replace XFree86 4.4rc2 with Xorg X11R6.7


  - there's no indication for a valgrind bug (it showed an error message
    when there *was* a crash; it doesn't show an error message now, and
    there is no crash any more)
  - it may have been an unnoticed bug in either freetype2 (that is solved
    now) or XFree86, or a compiler bug that doesn't occur any more
    because the code in question changed

Thanks for listening and sorry for the noise.  :-)
