[vigra_ext/NearestFeatureTransform.h:144]: (error) Resource leak: f

[dcb]

Source code is

    FILE * f = fopen(file,"wb+");
    if (f == NULL) {
        std::cerr << "enblend: error creating temporary file." << std::endl;
        exit(1);
    }
    size_t size = w*h;
    size_t itemsWritten = fwrite(ptr, sizeof(dist_t), size, f);
    if (itemsWritten < size) {
        std::cerr << "enblend: error writing to temporary file." << std::endl;
        perror("reason");
        exit(1);
    }

Suggest add missing call to fclose.

Theoretically this is a resource leak, but practical not: The code is not compiled (only when setting some additional DEBUG statements). And when it is compiled, the mentioned function is never called. So this change is purely cosmetic in a comment.
Nevertheless the functions was removed from the repo.
