_BLOCK_TYPE_IS_VALID（pHead-> nBlockUse）錯誤

Question

我在下面的代碼的最后一行發現了錯誤“ _BLOCK_TYPE_IS_VALID（pHead-> nBlockUse）”：

pixelCoorindateAndThreePoint* tempSpace = new pixelCoorindateAndThreePoint[possibleMaxSize];
while (sscanf(temp, "%f %f", &cam1x, &cam1y)){
    location = (int)(file->length*cam1y + cam1x);
    file->cam1cam2ThreeDPoints[(int)(file->length*cam1y + cam1x)] = new pixelCoorindateAndThreePoint;
        sscanf(temp, "%*f %*f %f %f %f %f %f \n",
            &(tempSpace->PixelCoordinateCam2.x),
            &(tempSpace->PixelCoordinateCam2.y),
            &(tempSpace->threePoints.x),
            &(tempSpace->threePoints.y),
            &(tempSpace->threePoints.z));

        file->cam1cam2ThreeDPoints[location] = tempSpace;
        tempSpace++;

    temp = strtok(NULL, "\n");
}
    delete[] tempSpace;

為什么會出現這樣的錯誤？ 由於我已將這些指針值復制到file->cam1cam2ThreeDPoints ，因此我應該能夠刪除tempSpace 。

Answer 1

tempSpace++; 更改指針。 您需要記住最初分配的指針，以使用它來調用delete 。
