The source of the error is:

After running the test once
go test
There is a directory .testwith the following content:

ll (find .test -type f)
-rw-------  1 rickard  staff    22B Jul 30 23:24 .test/location-full-dontfollow/test.txt
-rw-------  1 rickard  staff    10B Jul 30 23:24 .test/reopen-inotify/test.txt.rotated
-rw-------  1 rickard  staff    10B Jul 30 23:24 .test/reopen-polling/test.txt.rotated

This is the same on both OS X and Linux.

But running go test fails on OS X but not on Linux.

panic: readdirent: invalid argument

goroutine 16 [running]:
runtime.panic(0x13d1c0, 0x2082d61e0)
    /opt/boxen/homebrew/Cellar/go/1.3/libexec/src/pkg/runtime/panic.c:279 +0xf5

main.init()
    github.com/ActiveState/tail/_test/_testmain.go:76 +0x46

But after this the .test directory is gone and next run succeeds.

It seems that this is a Go + OS X 10.10 issue #8423.
