curl: ignoring 'options' when doing connection reuse

libcurl contains a significant logic flaw in its connection pool matching mechanism. When a transfer specifies a required authentication policy—such as a specific SASL mechanism e.g., ;AUTH=GSSAPI or a restricted set of SSH authentication types CURLOPTSSHAUTHTYPES—libcurl fails to verify these...
