Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

go version devel +38083c83a6 Thu Dec 7 23:37:46 2017 +0000 darwin/amd64

Does this issue reproduce with the latest release?

No

What operating system and processor architecture are you using (go env)?

GOARCH=“amd64” GOBIN=“” GOCACHE=“/Users/kevin/Library/Caches/go-build” GOEXE=“” GOHOSTARCH=“amd64” GOHOSTOS=“darwin” GOOS=“darwin” GOPATH=“/Users/kevin” GORACE=“” GOROOT=“/Users/kevin/go” GOTMPDIR=“” GOTOOLDIR=“/Users/kevin/go/pkg/tool/darwin_amd64” GCCGO=“gccgo” CC=“clang” CXX=“clang++” CGO_ENABLED=“1” CGO_CFLAGS=“-g -O2” CGO_CPPFLAGS=“” CGO_CXXFLAGS=“-g -O2” CGO_FFLAGS=“-g -O2” CGO_LDFLAGS=“-g -O2” PKG_CONFIG=“pkg-config” GOGCCFLAGS=“-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/var/folders/sf/fsn3_vgd0n98r0jb86bgp83r0000gn/T/go-build854984327=/tmp/go-build -gno-record-gcc-switches -fno-common”

Mac Sierra version 10.12.6. Using confluentinc/confluent-kafka-go@99a5addc08f7f0d0c20e51e0746f5af3434a5649.

What did you do?

I tried to compile a program that uses confluent-kafka-go and makes HTTP requests. Unfortunately it’s proprietary, but I can answer questions about it if need be.

I frequently recompile Go tip with the latest commit.

The compilation argument was:

go install -v -race ./...

What did you expect to see?

I expected the program to compile.

What did you see instead?

This error message (and only this error message):

$ go install -v -race ./...
# github.com/proprietary/proprietary/cmd/program
/Users/kevin/go/pkg/tool/darwin_amd64/link: /Users/kevin/go/pkg/tool/darwin_amd64/link: running dsymutil failed: signal: segmentation fault

I can blow away my cache if need be, or try a different commit, but I’m completely in the dark about how to trigger this, and worried that if I make changes (like e.g. blowing away the cache) I won’t be able to reliably reproduce the problem.

Running on my high end Macbook Pro which should have enough memory, CPU etc.
