I hope that's a typo--version 7.2.1 dates from before the dawn of Man.
On what platform is this?

And then what? You say the app dies. How? With a signal?

You're providing CURLOPT_POSTFIELDS twice. I'm not sure what the behaviour
is going to be in that case.

Note that integers as curl_easy_setopt must be of type long, not int.

There doesn't seem to be anything on that line that could cause a signal
causing application abort. It would be useful to know exactly what the
problem is at this point.

Nothing I can think of (unless you're using a 10 year old libcurl, of course).
A debugger should be able to give you more information about exactly what's
going wrong there.
