[go-nuts] Issue building binaries using cgo on macOS Sierra 10.12.4

Hello, Upgraded my mac to 10.12.4 yesterday, tried to run a binary built using go1.8. I immediately get Killed: 9 as output. The binary includes many C/C++ libraries via cgo but everything was fine under 10.12.3 I then built the binary using -ldflags -s and that was OK. I saw a similar issue
