UB constructing std::string with 0

[Amaroker]

String is an alias for std::string

OpenCOLLADA/COLLADAFramework/include/COLLADAFWPrerequisites.h

Line 18 in 6031fa9

typedef std::string String;

and these two lines will construct std::string with a null pointer, which is undefined behaviour:

OpenCOLLADA/COLLADAFramework/src/COLLADAFWRenderState.cpp

Line 53 in 6031fa9

return NULL;

OpenCOLLADA/COLLADAFramework/include/COLLADAFWMeshVertexData.h

Line 121 in 6031fa9

if ( index >= mInputInfosArray.getCount () ) return 0;
