            Bug ID: 38636
           Summary: Golang programs hang
           Product: Wine
           Version: 1.7.38
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

Log file with WINEDEBUG=+all

I've tried on several occasions to run Golang compiled programs.  I've tried
cross-compiled programs and programs compiled directly under Windows.  The
results are the same.  Things that involve "asynchronous" interaction
frequently hang.

Here is a dirt simple example:

package main

import (
  "log"
  "net/http"
)

func main() {
  log.Printf("Hello");

  resp, err := http.Get("http://www.google.com/")
  if err!=nil {
    log.Printf("Error: %v", err)
  } else {
    log.Printf("Response: %v", resp)
  }

  log.Printf("Done");
}

I'm attaching a log for this program with WINEDEBUG set to +all (since I have
no idea how to filter it down).  Since the output was enormous, I truncated it
to the last 1000 lines.  If you need more, let me know.

Any suggestions on how to workaround this or help to debug it?  I don't know
much about WINE, but I'll gladly help since this issue has really been a thorn
in my side.

If you want to build the executables under Linux, I posted a short guide to
making this work at:

https://groups.google.com/forum/#!searchin/golang-nuts/tiller/golang-nuts/AlQvxD7wv30/dNNDUuSyTgoJ

I set the following environment variables before compiling:

export GOOS=windows;
export GOARCH=386;
export CGO_ENABLED=1;
export CXX=i686-w64-mingw32-g++;
export CC=i686-w64-mingw32-gcc

I hope I covered everything.

Thanks.
