go: runtime: ThreadSanitizer CHECK failed

Please answer these questions before submitting your issue. Thanks!

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

$ go version
go version go1.11 linux/amd64

Does this issue reproduce with the latest release?

Yes.

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

$ go env
GOARCH="amd64"
GOBIN=""
GOCACHE="/home/benesch/.cache/go-build"
GOEXE=""
GOFLAGS=""

What did you do?

go get -u github.com/cockroachdb/cockroach
cd $(go env GOPATH)/src/github.com/cockroachdb/cockroach
make testrace PKG=./pkg/sql/logictest TESTS=TestLogic

This builds some C and C++ dependencies and ultimately runs:

go test -race -tags ' make x86_64_linux_gnu' -ldflags '-X github.com/cockroachdb/cockroach/pkg/build.typ=development -extldflags "" -X "github.com/cockroachdb/cockroach/pkg/build.tag=v2.2.0-alpha.00000000-793-g33c7d27d82-dirty" -X "github.com/cockroachdb/cockroach/pkg/build.rev=33c7d27d8216b543ac77f0fe39d440ebebfa9e70" -X "github.com/cockroachdb/cockroach/pkg/build.cgoTargetTriple=x86_64-linux-gnu"  ' -run "TestLogic"  -timeout 25m ./pkg/sql/logictest 

What did you expect to see?

Either a successful test run or an actual race.

What did you see instead?

FATAL: ThreadSanitizer CHECK failed: ./gotsan.cc:380 "((v)) > ((0))" (0x0, 0x0)

I tried to dig into this, but gotsan.cc is apparently generated deep inside the build process for the race detector and it wasn’t clear to me how to generate a gotsan.cc that matched my Go version.

Totally possible that this our (CockroachDB’s) bug, but there’s not a lot here for me to go on, so figured I’d file here and see if someone with more expertise in the race detector had any insight.
