Hi,
I could see the below messages as well in another crash:
(-) [Main Thread 7.293] (22412) IDirectFBSurfaceW:
IDirectFBSurface_Window_Release( 0x8c17c00 )
(-) [Main Thread 7.331] (22412) IDirectFBSurfaceW:
IDirectFBSurface_Window_Destruct( 0x8c17c00 )
(!) [Main Thread 7.331] (22412) *** Assertion [((FusionObject*)
object)->magic == D_MAGIC("FusionObject")] failed ***
[../../src/core/windows.h:83
in dfb_window_unref()]
There seems to be stray pointer which is corrupting the memory area.
Thanks
Suzuki
