Description
Please answer these questions before submitting your issue. Thanks!
What version of Go are you using (go version)?
go version go1.8 windows/amd64
with crosscompile GOOS: "linux", GOARCH: "arm"
What operating system and processor architecture are you using (go env)?
set GOARCH=amd64
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows
set GOPATH=E:\gopath
set GORACE=
set GOROOT=C:\Go
set GOTOOLDIR=C:\Go\pkg\tool\windows_amd64
set GCCGO=gccgo
set CC=gcc
set GOGCCFLAGS=-m64 -mthreads -fmessage-length=0
set CXX=g++
set CGO_ENABLED=1
set PKG_CONFIG=pkg-config
set CGO_CFLAGS=-g -O2
set CGO_CPPFLAGS=
set CGO_CXXFLAGS=-g -O2
set CGO_FFLAGS=-g -O2
set CGO_LDFLAGS=-g -O2
with crosscompile for
GOOS: "linux",
GOARCH: "arm"
--> for raspberry pi with no internal clock
What did you do?
Start the programm and call --> :8080/test
package main
import (
"log"
"net/http"
_ "net/http/pprof"
)
func main() {
http.HandleFunc("/test", testHandler)
panic(http.ListenAndServe(":8080", nil))
}
func testHandler(w http.ResponseWriter, r *http.Request) {
h := w.(http.Hijacker)
log.Println("calling hijack")
c, _, err := h.Hijack()
log.Println("hijack returned err=", err)
c.Close()
}
What did you expect to see?
No deadlock
What did you see instead?
Deadlock in call to
c, _, err := h.Hijack()
The reason for this deadlock is, that the clock is set to
1970/01/01
With newer date eg 2017/01/01 no deadlock.
For details, discussion and heapdump see:

@garyburd agreed, that this is probably an net/http issue
