[PATCH] D60008: Use binary write mode in WriteToFile function to avoid appended \r characters on Windows

[Vitaly Buka via Phabricator via llvm-commits]

vitalybuka added a comment.

Something like that but I would recommend something more generic

  extern "C" int LLVMFuzzerTestOneInput(const uint8_t *Data, size_t Size)
  {
    if (Size < 1000000)
     return 0;
  
    // or any other simple hash
    Sum = Size;
    for (i = 0 to Size )
       Sum += data[i]
  
    if (Sum % 100 == 19)
        abort();
  
    return 0;
  }

rm -rf  SOME_UNIQUE_PREFIX*
run with -max_len=2000000 -artifact_prefix=SOME_UNIQUE_PREFIX 
it should crash quickly

retry on SOME_UNIQUE_PREFIX* 
so if any character in input is altered by Write/Read it should stop being reproducible.
