带autorelase的Objc内存崩溃

我一直在搜索我的所有代码,但找不到这次崩溃的根源:

*** __NSAutoreleaseFreedObject(): release of previously deallocated object (0x1008ad200) ignored
*** __NSAutoreleaseFreedObject(): release of previously deallocated object (0x1008ab200) ignored
*** __NSAutoreleaseFreedObject(): release of previously deallocated object (0x1008a8c00) ignored

不好的是,initWithCoder没有被调用的原因是它与[super initWithCoder:]有问题;这仍然让我发疯。我看了一下,指针和NSData对象是哪里出了问题:

    vertices = malloc(size_point3D * vertexCount);
    textureCoords = malloc(size_point2D * textureCount);
    normals = malloc(size_point3D * normalCount);
    faces = malloc(sizeof(GLuint) * faceCount);


    NSData *vertexData = [[NSData alloc] initWithData:[coder decodeObjectForKey:@"vertices"]];
    NSData *textureData = [[NSData alloc] initWithData:[coder decodeObjectForKey:@"textureCoords"]];
    NSData *normalData = [[NSData alloc] initWithData:[coder decodeObjectForKey:@"normals"]];
    NSData *faceData = [[NSData alloc] initWithData:[coder decodeObjectForKey:@"faces"]];


    memcpy(vertices, [vertexData bytes],  sizeof(point3D) * vertexCount);
    memcpy(textureCoords, [textureData bytes], sizeof(point2D) * textureCount);
    memcpy(normals, [normalData bytes], sizeof(point3D) * normalCount);
    memcpy(faces, [faceData bytes], sizeof(GLuint) * faceCount);

    [vertexData release];
    [textureData release];
    [normalData release];
    [faceData release];

我试过保留这部分的所有内容(甚至是字符串),但没有任何帮助。
