Output from go version

    go version go1.5 linux/amd64


The problem is related to compilation of golang/benchmarks (i.e.

I tried to run go build (then go install) as suggested by README, to build the benchmark executable which runs the benchmark.

Here suggests the existence of StartTrace and StopTrace in runtime/pprof but they do not exist.

What I expect to see

bench executable created in $GOPATH/bin/ (no output)

driver/driver.go:91: undefined: pprof.StartTrace
driver/driver.go:95: undefined: pprof.StopTrace
