The scenario is as follows.
My application is using HTTPS and sending HEAD request, and is getting
the above response. I am new for curl lib and am not having much
understanding of HTTP protocols versions. Also as my application is
using HTTPs I can not see the wire-capture. Is there anyway I can
setup server as I can see this problem with one of my customer
servers. Below is the backtrace I am getting

Please send us a minimal self-contained example that we can use to
reproduce. I don't know if this was mentioned already but in your case
even though you chose CURLOPT_NOBODY [1] the data still goes to the
write function (CURLOPT_WRITEFUNCTION [2], CURLOPT_WRITEDATA [3]) since
there doesn't appear to be a proper response. I guess an issue is
whether or not that's correct for NOBODY but also I guess on your end
your write function is probably crashing. You'd have to build in
debugging mode to get a good stack that you can walk through.
And please stop top-posting [4], it makes the thread difficult to
follow. My apologies if any of the above has already been covered the
thread was maddening to read so I just skimmed it.
