JSONCPP-SRC-0.5.0.TAR.GZ SOURCE Error!!!

Recently in the completion of the establishment, the use of the JsonCpp0.5.0 version number of the source code!

According to the online installation configuration tutorial, set up a good environment can be used!

Here will not waste space to how to build the development environment! Let's go to Google for a moment!

When parsing a JSON file. The program always goes wrong somewhere!

Started to think that the TXT file format is not correct, but also deliberately found a JSON file to engage! This sends the JSON file and executes it!

Is it really a file problem! I'm simplifying my txt file, but it's still a problem, and it's not in my code. is the source of Jsoncpp has a problem! I can't believe it!!

I loaded the source into my project file, once again debug execution, debugging time to locate the problem!

In Json_reader.cpp

BOOL Reader::d ecodedouble (Token &token) {   Double value = 0;   const int buffersize = +;   int count;   int length = Int (Token.end_-token.start_);   if (length <= buffersize)   {      Char buffer[buffersize];      memcpy (buffer, token.start_, length);      Buffer[length] = 0;      Count = sscanf (buffer, "%LF", &value);   }   else   {      std::string buffer (Token.start_, token.end_);      Count = sscanf (Buffer.c_str (), "%lf", &value);   if (count! = 1)      return Adderror ("'" + std::string (Token.start_, Token.end_) + "is not a number.", token); 
   currentvalue () = value;   return true;}

The problem is actually very easy, that is, array access to cross the border!

It would be nice to change the inferred statement in if to length < buffersize!

Test example passed! The correct resolution!
