As documented in the CURLOPT_CONNECT_ONLY man page which seems relevant since
your example code uses it:
Transfers marked connect only do not reuse any existing connections and
connections marked connect only are not allowed to get reused.

That should probably be handled better, but you seem to be using a debug build
and then we sometimes make it do things with asserts like that.
