           Summary: _cairo_ft_unscaled_font_fini does not decrement
           Product: cairo
           Version: cvs
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ft font backend
        AssignedTo: otaylor at redhat.com

There's a logic bug in the handling of font_map->num_open_faces.

It should get decremented for every call to FT_Done_Face, but
_cairo_ft_unscaled_font_fini calls FT_Done_Face without decrementing

I think I introduced this bug with the hash rewrite. I also think an
assert statement in the cairo_debug_reset_static_data path should catch
it. I'll look into both detecting and fixing this bug.
