Hello,

thanks for your previous immediate response.

I am trying now to test the persistant connections feature. So, I wrote
the following simple program (a copy of your example):
_______________________________________________________________________________________________

//Common includes
#include <iostream.h>

//CURL includes
 #include <curl/curl.h>
 #include <curl/types.h>
 #include <curl/easy.h>

main(int argc, char *argv[])
{
  CURL *curl;
  CURLcode res;
  FILE *ftpfile, *ftpls;

  /* local file name to store the file as */
  ftpfile = fopen("readme.txt", "wb"); /* b is binary for win */
 ftpls = fopen("ftpls.txt", "wb");

   struct curl_slist* list=NULL;
   list = curl_slist_append(list, "cwd usr");

  curl = curl_easy_init();
  if(curl) {
 cout << "TRY TO CONNECT" << endl;

  curl_easy_setopt(curl, CURLOPT_URL, "ftp://myhost/readme..txt");
  curl_easy_setopt(curl, CURLOPT_FILE, ftpfile);
  curl_easy_setopt(curl, CURLOPT_USERPWD, "dimitris:dimitris");

// curl_easy_setopt(curl, CURLOPT_FTPLISTONLY, 1);

  curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);
 cout << "Before perform" << endl;

    res = curl_easy_perform(curl);
 cout << "Error: " << res << endl;

 cout << list->data << endl;

 curl_easy_setopt(curl, CURLOPT_URL, "ftp://myhost");
 curl_easy_setopt(curl, CURLOPT_FILE, ftpls);
 curl_easy_setopt(curl, CURLOPT_USERPWD, "dimitris:dimitris");
 curl_easy_setopt(curl, CURLOPT_QUOTE, list);

 res = curl_easy_perform(curl);
  cout << "Error: " << res << endl;

 curl_slist_free_all(list);

    /* always cleanup */
   curl_easy_cleanup(curl);
  }

  fclose(ftpfile); /* close the local file */
  fclose(ftpls);

  return 0;
}
__________________________________________________________________________________________

When I execute the above, it crashes at the first call of
"curl_easy_perform". I debugged with dbx and I found that it crashes
inside the "Curl_getaddrinfo", at line 831 of the "ftp.c" :

831: if(gethostbyaddr_r((char *) &address,
                         sizeof(address), AF_INET,
                         (struct hostent *)hostent_buf,
                         hostent_buf + sizeof(*answer)))

   (DBX output)
    0 ftp_pasv_verbose(conn = 0x14003f800, addr = 0x14007e030, newhost =
0x11fffeeb8 = "146.124.12.49", port = 58599) ["ftp.c":821,
0x3ffbffed2b8]
       1 ftp_use_pasv(conn = 0x14003f800) ["ftp.c":1351, 0x3ffbffedb58]
       2 ftp_perform(conn = 0x14003f800) ["ftp.c":1477, 0x3ffbffede4c]
       3 Curl_ftp(conn = 0x14003f800) ["ftp.c":1898, 0x3ffbffeeaa0]
       4 Curl_do(conn = 0x14003f800) ["url.c":2164, 0x3ffbfff2bd4]
       5 Curl_perform(data = 0x140053040) ["transfer.c":927,
0x3ffbfffc178]
       6 curl_easy_perform(curl = 0x140053040) ["easy.c":233,
0x3ffbfffcbac]
       7 main(argc = 1, argv = 0x11ffff0e8) ["ftp_application.cxx":48,
0x1200020e4]

The strangest thing is that your example runs without a problem. :-!

Thanks,
Dimitris
