Question

我在一个项目上遇到了一个非常奇怪的错误我正在编写代码。这是错误（使用valgrind）

我会在我的同事计算机（实际上是MACOSX）上添加它，它完全正常。

这是我们的（awfull）main，第70行是我们.c文件中main的第一行:(还是WIP请原谅我在这里发生的所有狗屎^^）

int main(int argc, char* argv[]) {
    printf("derp\n");
    int i = 0;
    char lines[MAXLINES][BUFSIZ];
    char* path[MAXLINES];

    printf("derp\n");
    FILE *fp = fopen("./Images/125/DBtexte.txt", "r");

    if (fp == 0) {
        fprintf(stderr, "failed to open DBtexte\n");
        exit(1);
    }

    printf("derp\n");
    while (i < MAXLINES && fgets(lines[i], sizeof(lines[0]), fp)) {
        lines[i][strlen(lines[i])-1] = '\0';
        i = i + 1;
    }

    i = 0;
    printf("derp\n");
    while(strcmp(lines[i],"\0"))
        i++;
    char *folder = "./Images/125/";
    for (size_t j = 0; j<(size_t)i; j++) {
        char *temp = lines[j];
        char *temp2 = (char *) malloc(1 + strlen(folder)+ strlen(temp));
        strcat(temp2,folder);
        strcat(temp2,temp);
        path[j] = temp2;
        //printf("%s\n",path[j]);
    }
    fclose(fp);
    int *visage = faces(i-1,i);
    printf("\nTHE FACE IS A LIE\n");
    /*if (argc < 2)
            errx(2, "Usage:\n%s <path>", argv[0]);
    SDL_Surface* image = load_image(argv[1]);
    display_image(image);
    ToGray(image);
    display_image(image);
    Binarize(image);
    display_image(image); */
    printf("ONSTART\n");
    strongClassifier* yolo;

    yolo = adaboost(path, visage, 124, 1, 20);


    //int len;
    //haarRecord* haarOutput;
    //haarOutput = processImage(image, &len);
    //display_haar(haarOutput, len);
    //SDL_SaveBMP(image, "./ToGray.bmp");
    return 0;
}

真的期待你的帮助：）
