I apologise for how harsh my tone here was -- re-reading, it was way
more coarse than it should've been; I was frustrated at the time of
writing and too much of that came out in my response.
I did test beyond Docker (several other Go projects, and all directly
via the Go toolchain "go get", "go build", etc); I don't have lots of
extra time especially since gccgo isn't involved in my day-to-day
Generally, I'm concerned that gccgo claims to be language-compatible
but not necessarily toolchain-compatible (compiler flags come to mind,
since that's what the Docker build system ended up needing changes to
build under gccgo).
Separate from that, it concerns me a great deal that Docker's
integration tests fail (and the daemon itself segfaults) when I
compile it via gccgo. I'm not saying this is necessarily
representative, but it's an important point to consider IMO, since I
don't think it's going to be the only package that has runtime issues
when compiled with a completely different buildchain.

We did push Go 1.4.1 to experimental in Jan, but I'll try to find some
cycles to get 1.4.2 up there too; thanks for the prod.
I'll see if I can get the IBM Docker folks to do some testing on their
side, too. Last I asked, they couldn't reproduce failures with a
gccgo-built daemon, but I'll see if they've specifically run
upstream's test-integration-cli suite against it (since that's the
workload that gets me a segfaulting daemon within just a few tests).
