Raised issue upstream:
https://github.com/curl/curl/issues/6266

and got upstream response pointer to:
https://github.com/curl/curl/blob/0d75bf9ae99f62ac5aab46cd281fd5a7e0760a69/lib/vtls/openssl.c#L4244-L4259
"For debug builds be a little stricter and error on any SSL_ERROR_SYSCALL.
For example a server may have closed the connection abruptly without a 
close_notify alert.

For compatibility with older peers we don't do this by default.
https://github.com/curl/curl/issues/4624

We can use this to gauge how many users may be affected, and if it goes ok 
eventually transition to allow in dev and release with the newest OpenSSL:
#if (OPENSSL_VERSION_NUMBER >= 0x10101000L)"

so will disable this in a new Cygwin release which will be uploaded soon.

*Curl users should be aware that deviations from strict protocol are deprecated 
and will be reported as errors unconditionally in a near future release.*
