Go builds failing in 14.04

Prior to CircleCI rolling out Ubuntu 14.04 everywhere, we were building our Go projects on 12.04 and installing go 1.6.x manually in our circle configuration.

With 14.04 now as the default build environment, our previously passing projects are now failing with little explanation. The tests simply fails before even running TestMain. Downgrading our build environments to 12.04 brings them back to life.

Furthermore, running the tests manually while SSH’d into the build container succeeds. Output on failure is simply:

go test -v [REDACTED}
exit status 1
FAIL [REDACTED] 0.024s

go test -v [REDACTED] returned exit code 1

Anyone else running into similar issues?
