Golang runtime error with macOS Sierra
If you are on Golang 1.6 or older, you may meet a panic error when you try to build or test your programme or anything else related with runtime:
fatal error: unexpected signal during runtime execution
There is a post about the issue in golang-nuts: [https://groups.google.com/forum/#!topic/golang-nuts/XaVT6fi1g30]. The bug is fixed in Golang 1.7, so just upgrade to 1.7 and you will be happy.
