$ gotip version
go version devel +ff99a61e5e Fri Oct 19 14:11:52 2018 +0000 linux/amd64

The go/types test where it typechecks the whole standard library is currently failing on the crypto/tls package:

$ cd src/go/types
$ gotip test -run=Stdlib
--- FAIL: TestStdlib (9.24s)
    stdlib_test.go:243: /home/alberto/go/src/crypto/tls/handshake_client_test.go:1651:76: user-defined object without package: func (interface).Error() string
    stdlib_test.go:243: /home/alberto/go/src/crypto/tls/handshake_server_test.go:1439:76: user-defined object without package: func (interface).Error() string
FAIL
exit status 1
FAIL	go/types	9.263s

Spotted on the longtest builder.

Yes, I just noticed this one, too, locally. Seems new.

@griesemer I would like to keep the longtest builder green. Should I send a CL ignoring that error for the tls package? Obviously I won't bother if you plan to fix this in the near future.

This appears to be a subtle issue - won't have time today to track this down. Temporarily disabled part of the failing test per the above CL.

Keeps the longtest builder green for now.
Proper fix to come ASAP.

Also, reword an internal comment that could easily be misread.

Updates #28282.
