trunk with lucid toolkit
valgrind ./temacs -Q
gives this warning (not sure exactly when, just playing with the menus
and tooltips, the only "editing" action was to run a grep)

==2341== Conditional jump or move depends on uninitialised value(s)
==2341==    at 0x44CDDA: draw_glyphs (xdisp.c:22981)
==2341==    by 0x44D9FC: expose_area (xdisp.c:27401)

==2341==  Uninitialised value was created by a stack allocation
==2341==    at 0x44AAD3: draw_glyphs (xdisp.c:22835)

The warning is for this:
        if (check_mouse_face
              && mouse_beg_col < start && mouse_end_col > i)

it looks like mouse_beg_col and mouse_end_col could be left uninitialized a few 
lines above.
