      Yes, you were right. After I found out that the very same binary worked
      on my Solaris Express install (the -dev branch of Solaris), I had a
      harder look at the most recently installed patches.
      There was one for fontconfig, and the last functions called were for
      fontconfig, the evidence was overwhelming, it was the culprit. Once I
      had it backed out, the binary worked.

      FWIW, tt's that one, out 3 days ago:
      123495-02 X11 6.6.2_x86: fontconfig patch

      I'm back to -01, which works.

      Yes, it's a JDS thing, it's also displayed for other GNOME apps on Solaris.

      On Solaris 10, it's where freetype and Xrender live, so it's needed at
      build time, IIRC, because else, some dependencies won't link correctly.
      Actually, I did that a while ago, and didn't try again since them, so
      maybe it's not needed anymore (the .pc files should provide the correct
      paths). If you want, I'll build again to confirm that.

      Definitely not a vim issue, sorry for bothering you, I'll be sure to
      open a case with Sun about that on Monday.

      Thanks for your answer!
