Intermittent go test crashes on ppc64el

[Casey Marshall]

Platform/version:
Ubuntu 14.04
ii gccgo 4:4.9-1ubuntu6 ppc64el Go compiler, based on the GCC backend
ii gccgo-4.9 4.9-20140406-0ubuntu1 ppc64el GNU Go compiler
ii gccgo-go 1.2.1-0ubuntu1 ppc64el Go tool for use with gccgo
Linux borbein-03 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:09:21 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux

When I try to run all the juju unit tests (master 1060f2dce3d5f7c6bfc72f203457bfdced794b45) with 'make check' or 'go test ./...', I get a go tool error like this: http://paste.ubuntu.com/8216719/

I am able to run smaller subset paths, like ./cmd/... however.

Sorry Casey, I don't know where you got that revision of the compiler from, but it's too old and busted. Try the one from trusty-proposed.
