I would propose three different things that can help you go forward.

1. build with debug enabled and debug-symbols present so that when you get a
crash, you can view arguments and local variables. It helps diagnosing. And
when you show us stack traces, we can tell a lot more about what was going on.

2. switch back to a simpler logic and code (that works) as a test and then
work yourself forward again as then when/if you get a crash again you know
what introduced the crash. You should be able to get a working libcurl using
function for simple things almost based entirely on provided examples.

3. if these two steps fail, or perhaps in parallel, create a separate
application that is not tied to your real application that works similar as
your real application but is a separate thing that you write to work with a
public URL and that once it reproduces the problem, you can share with us and
we can help assist in the debugging.

Also: make sure you're not working with an ancient libcurl version.
