The SEC_E_BUFFER TOO_SMALL seems to be the issue mentioned here: Waffle/waffle#128 (comment)
(confirmed by wireshark capture below)

related MS-bug report

The SEC_E_MESSAGE_ALTERED likely is another issue.

  • Running the tests on Win8.1 or Server 2012 R2 (ONLY these versions) results in sporadic
    build failures with the error codes mentioned in the title
:a
cargo test validation_failure_is_permanent && goto a
pause
  • Running them on Win7, Server 2008, Win8, Server 2012, Win10, Server 2016 (Preview)
    does not result in sporadic failures.
  • Removing
    TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 and TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 from the schannel SSL cipher suites order, results in the disappearance of this bug.
