So run it with a debugger and see where the crash occurs!

No, COOKIEFILE and COOKIEJAR are easy to use and really don't offer any
surprises. They don't cause any crashes either if you use them as documented.

A crash is a crash, and your OS and debugger should make it informative
especially if you rebuild your app and libcurl with debug symbols present.

If you'd post your full program here so that we can try it as well, then
things would be much easier. Or potentially an example that at least repeats
your problem.
