I'm working through some tutorial code for the "Go Web Programming" book by Sau Sheong Chang (Manning, 2016) and got "fatal error: unexpected signal during runtime execution" trying to run go build once, then tried a second time a minute later without trying anything and it worked. The code I was building is here.

I want to reiterate: this happened just once. A subsequent run of go build without changing anything worked as expected. Unfortunately I have virtually no information to provide besides a cut and paste of the stack trace below because I was unable to reproduce. I saw an issue had been opened with what appeared to be the same bug, but that thread indicated that if it appeared on real hardware (yes: 2013 MacBook Pro) that a new issue should be opened.

Go 1.6.2 doesn't support macOS 10.12, please upgrade to Go 1.7.
