    0xC0000005: Access violation reading location 0x00000010

    when i compile program i dont get any error but when program starts up it gives this error. 0xC0000005: Access violation reading location 0x00000010

    only warning at debugin mode
    warning LNK4098: defaultlib 'MSVCRTD' conflicts with use of other libs; use /NODEFAULTLIB:library

    i ignore this library (msvcrtd.lib). this time there is no error or warning. but program at the start up gives again this error" 0xC0000005: Access violation reading location 0x00000010 ". i use 3 library in my code first one is opengl others are assimp and SDL.

    You're probably trying to access a NULL pointer somewhere, most likely one which you think points to a structure or array, specifically a field 16 bytes after the pointer itself.

    When it crashes use the debugger to find out the line causing the crash and the NULL pointer you're trying to use.

    thanks you for reply. i think that error arises from Assimp library,loading 3d models.

    Code:
    /////////////////////////////////////////////
    //// DefaultLogger.cpp                                         Assimp library ( third party library)
    ////////////////////////////////////////////
    void Logger::info(const std::string &message)	{
    	
    	// SECURITY FIX: otherwise it's easy to produce overruns ...
    	if (message.length()>MAX_LOG_MESSAGE_LENGTH) {
    		ai_assert(false);
    		return;
    	}
    	return OnInfo(message.c_str());       // compiler shows this point
    }

    Code:
    /////////////////////////////////////////////
    // main.cpp                                           my code
    ///////////////////
    
    class Model{
    	Assimp::Importer* importer;
    	const aiScene* data;
    public:
    	Model(const char* str, unsigned int flag){
    		
    		importer = new Assimp::Importer;
    		data = importer->ReadFile(str,flag);
    		//if(data==NULL)
    		//	std::cout<<"ReadFile() error\n";*/
    	}
    	
    	
    	void draw(){
    		/*
    		glEnableClientState(GL_VERTEX_ARRAY);
    		glVertexPointer( 3,GL_FLOAT,0,data->mMeshes[0]->mVertices);
    		unsigned int* indices = new unsigned int[data->mMeshes[0]->mNumFaces * 3];
    		for(unsigned int i=0,j=0; i<data->mMeshes[0]->mNumFaces; ++i,j+=3)
    		{
    			indices[j]   = data->mMeshes[0]->mFaces[i].mIndices[0];
    			indices[j+1] = data->mMeshes[0]->mFaces[i].mIndices[1];
    			indices[j+2] = data->mMeshes[0]->mFaces[i].mIndices[2];
    		}
    		glDrawElements( GL_TRIANGLES,3*data->mMeshes[0]->mNumFaces,GL_UNSIGNED_INT,indices);
    */
    	}
    };
    
    Model m("Building33.3DS",aiProcess_Triangulate            |
            aiProcess_JoinIdenticalVertices  |
            aiProcess_SortByPType);
    
    
    int main(int argc, char* argv[]){
    char c;
    
    
    std::cin>>c;
    	return 0;
    }
