<p class="MsoNormal"><span style="color:black">Hi Liviu, <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">Found the exact issue what causes the crash.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">In start_async_http_req, under case PUT/POST, we have the following code
</span><span style="color:blue">blue color </span><span style="color:black">by default.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">But for my project scenario, I need to add call-id header too here, including that code
</span><span style="color:red">in red color </span><span style="color:black">for your reference.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:blue">if (req_ctype) {<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"> sprintf(print_buff, "Content-Type: %s", req_ctype);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"> header_list = curl_slist_append(header_list, print_buff);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"> </span><span style="color:red">sprintf(print_buff, "Call-Id: %s", instanceId);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:red"> header_list = curl_slist_append(header_list, print_buff);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"> w_curl_easy_setopt(handle, CURLOPT_HTTPHEADER, header_list);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"> }<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">If I try by removing the Call-Id header in the curl-slist, then it works perfectly fine in case of POST as well as PUT.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">How can I overcome this situation? Your guidance would help me a lot.<o:p></o:p></span></p>
