Hi Umesh,
there have been changes in this area but I can not clearly identify if
you are being helped with them.
Simple solution: try with the latest DirectFB (1.4.3) and fusion (8.1.1)
and see if your problem is gone.

Hi,
I am using Directfb 1.2.7 with multiapp enabled and fusion 8.0.0.
My application is working fine with multi-app environment. But during
release of directfb handle, I am getting following error
*** glibc detected *** Video: free(): invalid pointer: 0x0044e340 ***
(!) [ 820: 760.007] --> Caught signal 6 (unknown origin) <--
When any other application using graphics layers is run during my
video application, I am getting above issue during release of directfb
handle in my video application.
When debugged directfb, I see issue with src/core/local_surface_pool.c
static DFBResult
localLeavePool( CoreSurfacePool *pool,
void *pool_data,
void *pool_local )
{
CoreSurfaceAllocation *allocation;
LocalPoolLocalData *local = pool_local;
LocalAllocationData *data;
DFBResult res;
int i;
D_MAGIC_ASSERT( pool, CoreSurfacePool );
D_ASSERT( pool_local != NULL );
res = fusion_call_destroy( &local->call );
/* remove the local allocations */
fusion_vector_foreach (allocation, i, pool->allocs) {
data = allocation->data;
D_FREE( data->addr );
}
return res;
}
I think there is issue with the way this pointer is freed as when I
run other application with just directfb initialization and creation,
direcfb release is working fine in my video application.
Is this a issue with multiapp support of directfb?
Is there any patch for this?

Umesh
