Subject: Bug#355715: libcurl 7.15.2-2 seriously broken in unstable

...

Description:
The library raises an exception after uploading a file via http post,
7.15.1 worked fine

this is the code from the app i use,

                while ( (pMessage = curl_multi_info_read(m_CurlStack, (int *)&iQueue)) )
                {
                        if ( pMessage->msg == CURLMSG_DONE )
                        {
                                NormanContext *norm;
                                char * szUrl;

                curl_easy_getinfo(pMessage->easy_handle,
CURLINFO_PRIVATE, (char * *) &norm);
                                if ( pMessage->data.result )
                                {
                    logInfo("Upload Error %s on getting file %s \n",
curl_easy_strerror(pMessage->data.result), norm->getMD5Sum());
                                } else
                                {
                                        curl_easy_getinfo(pMessage->easy_handle, CURLINFO_EFFECTIVE_URL, &szUrl);
                                        logInfo("Submitted file %s to sandbox \n",norm->getMD5Sum());
                                }
                                CURL *curl = pMessage->easy_handle;
                                curl_multi_remove_handle(m_CurlStack, pMessage->easy_handle);
                                delete norm;
                                curl_easy_cleanup(curl);
                                --m_Queued;
                        }
                }

here is the backtrace

*** glibc detected *** double free or corruption (!prev): 0x0809b7f8 ***

#10 0x00000000 in ?? ()

To reproduce, run nepenthes with submit-norman and trigger a file
download using x2 (i know this is not really trivial).

as mentioned before, previous versions of curl worked _fine_
