Similar (same?) problem here with 7.12.2 dll and an old version of Visual C++.
WinXP as well.
No clue yet. Haven't tried much due to lack of capability.

  Subject: FTP Upload problem : crash

  Hello,

  I have a program I am developing with curl but am having troubles uploading a file.

  These are the steps I am currently taking in my program. I would appreciate if anyone could point out any thing I am doing wrong.

  OS: WinXP
  Curl Version: 7.11.1
  IDE: Visual C++ .NET

          char m_szErrMsgLast[1024];
          FILE *pInput = fopen(szLocalFile, "r"); // Open the local file (C:\tmp.txt would suffice here)
          if (NULL == pInput)
                  throw "Unable to open local file";
          long fsize = filelength(fileno (pInput));

          curl_global_init(CURL_GLOBAL_ALL);

          void * m_pCurl = curl_easy_init();

          // set the errror buffer
          curl_easy_setopt(m_pCurl, CURLOPT_ERRORBUFFER, m_szErrMsgLast);

          //Set the passive mode
          curl_easy_setopt(m_pCurl, CURLOPT_FTP_USE_EPSV, TRUE);

          // enable uploading
          curl_easy_setopt(m_pCurl, CURLOPT_UPLOAD, TRUE) ;

          // Set the URL to transmit to (the value of this is remotefile.txt)
          curl_easy_setopt(m_pCurl, CURLOPT_URL, szRemoteFile);

          // Set a pointer to the file to be sent, and set the size
          curl_easy_setopt(m_pCurl, CURLOPT_INFILE, pInput);
        curl_easy_setopt(m_pCurl, CURLOPT_INFILESIZE, fsize);

          // Want to watch what happens!
          curl_easy_setopt(m_pCurl, CURLOPT_VERBOSE, TRUE);
                  
          // Fire away!
          res = curl_easy_perform(m_pCurl);

  What results is a crash in curl. The curl_easy_preform call at the end throws an exception:
  (I replaced any identifying information with garbage numbers, but the messages are untouched.

  * About to connect() to 111.22.33.44 port 21

  This pauses for a while, I assume the file transfer attempts to take place.

  Then the excetion is thrown:

  + ex { _COMPlusExceptionCode=-532459699 _className="System.NullReferenceException" _exceptionMethod=<undefined value> ...} System.Exception
  + "System.NullReferenceException: Object reference not set to an instance of an object.

  Any advice at all as to what I may be doing wrone here would be GREATLY appreciated!

  Cheers,
  joe
