What did you do?
If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.
We are working with CloudFoundry and using Spiff and Yaml2Json programs written in Go.
https://github.com/cloudfoundry-incubator/spiff
https://github.com/bronze1man/yaml2json
What did you expect to see?
spiff file1.yml file2.yml | yaml2json
Expect to see a json document on stdout.
What did you see instead?
Since update to macOS Sierra both tools mentioned above show this MSpanList_Insert error sometimes. The problem occurs sporadically and is not reproducible. Both tools were re-compiled using Go 1.7.1.
