mpi动态数组内存分配

Question

您好我正在尝试在灰度pgm图像上应用滤镜：

int contor = 0;
char *magicNumber;
char *metaData;
int imageWidth = 0, imageHeight = 0, valueRange = 0;
int *imageData;
while (EOF != fscanf(fp2, "%[^\n]\n", line))
{
    if(contor == 0)
    {
        magicNumber = (char*)malloc((1 + strlen(line)) * sizeof(char));
        strcpy(magicNumber, line);
        magicNumber[strlen(magicNumber)] = '\0';
    }
    else if (contor == 1)
    {
        metaData = (char*)malloc((1 + strlen(line)) * sizeof(char));
        strcpy(metaData, line);
        metaData[strlen(metaData)] = '\0';
    }
    else if (contor == 2)
    {
        token = strtok(line, " ");
        imageWidth = atoi(token);
        token = strtok(NULL, " ");
        imageHeight = atoi(token);
        imageData = (int*)malloc(imageWidth * imageHeight * sizeof(int));
    }
    else if (contor == 3)
    {
        valueRange = atoi(line);
    }
    else
    {
        printf("Should put value %d in imageData at index %d\n", atoi(line), contor);
        //imageData[contor-4] = atoi(line);
    }
    contor++;
}

我的代码在imageData内存分配中断。正确读取宽度和高度并将其转换为int;

谁能告诉我我做错了什么？
