I`m note sure where the problem comes from but with IDE 5.0 + gdb 7.4 + DSF when starting a debug session the debugger 
is unable to load/find the symbols for shared library specified in Shared Librairies tab.  But with CDI it works

The extra paths are c:\helios_6_5_0\logc\librairies\lib and c:\opt\poco_1.4.2p_1_QNX650\lib.

With DSF framework
