   M /trunk/pkg/dem/Engine/StandAloneEngine/GlobalStiffnessCounter.cpp

No idea why dynamic_cast fails while static_cast works in TriaxialCompressionEngine:275 and GlobalStiffnessCounter:63 when casting to NormalShearInteraction. We will use static_cast for now... 

Added informative message in case when log4cxx enters infinite loop while crashing on exit
