I just found a new way to workaround this problem with the state being replaced.
The attached patch introduces a new field in the internal session structure to keep track of the currently cached session. With this change the invalid memory access is gone and the Schannel Credential handle (session) is still freed if the connection could not be established. (This was the original reason for the cleanup code in Curl_schannel_shutdown.)
