Well, this is interesting. After some more digging in df_fire I found
what appears to be some stack corruption happening when calling
dfb_gfxcard_fillrectangles from IDirectFBSurface_Clear. The stack
looks as follows:
(gdb) bt
#0 dfb_gfxcard_fillrectangles (rects=0x2eed8, num=2, state=0x12888)
at gfxcard.c:995
#1 0x401f0d8c in IDirectFBSurface_Clear (thiz=0x1bb28, r=0 '\000',
g=0 '\000', b=0 '\000', a=255 '\377') at idirectfbsurface.c:729
#2 0x00009608 in init_application (argc=0xbec75b24, argv=0xbec75b20)
at df_fire.c:405
#3 0x000087f8 in main (argc=1, argv=0xbec75d84) at df_fire.c:88
but dfb_gfxcard_fillrectangles's parameters somehow magically gets
transformed from this:
(gdb) up
#1 0x401f0d8c in IDirectFBSurface_Clear (thiz=0x1bb28, r=0 '\000',
g=0 '\000', b=0 '\000', a=255 '\377') at idirectfbsurface.c:729
729 dfb_gfxcard_fillrectangles( &data->area.current, 1, &data->state );
(gdb) print &data->area.current
$16 = (DFBRectangle *) 0x1bc6c
(gdb) print data->area.current
$17 = {x = 0, y = 0, w = 320, h = 240}
into this:
(gdb) down
#0 dfb_gfxcard_fillrectangles (rects=0x2eed8, num=2, state=0x12888)
at gfxcard.c:995
995 dfb_state_start_drawing( state, card );
(gdb) print *rects
$18 = {x = 0, y = 9881, w = 0, h = 0}
WTF? gcc version 4.5.3 (Buildroot 2011.05). Compiler bug? Maybe I
should move this discussion to the devel list.
