I was successful in bringing up DFB-1.4.17 7 & DFB-1.5.3 with linux-fusion
versions 8.7.0 & 8.10.4 respectively on Set Top Box platform.
Now I am bringing up DFB-1.6.3 in multi-app mode with linux-fusion-9.0.0
on the same platform.
While bringing up DFB-1.6.3,especially when master process is getting
initialized, I found that the exported function Core_AsyncCall_Handler
passed in as argument to fusion_call_init() .In this function
fusion_call_init() the handler is being resolved using
direct_trace_lookup_symbol_at().*However I am observing that the
**direct_trace_lookup_symbol_at()
is returning NULL.This is happening for both enable-debug & disable-debug
variants for all the shared functions exported using fusion_call_init() &
fusion_call_init3().Later when slave process initializing DFB its invoking
shared functions via fusion message loop thread.Now it doesn't execute the
shared functions.As a result all the fusionees are getting destroyed.*

Does anyone have any idea on why this is happening?
