Version

Microsoft Windows [Version 10.0.15063]
go version go1.8.3 linux/amd64

Steps to reproduce

  1. Create a new go project
  2. Put the following code in main.go:
package main

import (
	"fmt"
	"log"
	"os"

	"github.com/boltdb/bolt"
)

func main() {
	os.Remove("test.db")
	db, err := bolt.Open("test.db", 0600, nil)
	if err != nil {
		log.Fatal(err)
	}
	defer db.Close()

	db.Update(func(tx *bolt.Tx) error {
		_, err := tx.CreateBucket([]byte("MyBucket"))
		if err != nil {
			return fmt.Errorf("create bucket: %s", err)
		}
		return err
	})

	db.View(func(tx *bolt.Tx) error {
		b := tx.Bucket([]byte("MyBucket"))

		c := b.Cursor()

		c.Seek([]byte("test"))

		return nil
	})
	os.Remove("test.db")
}
  1. ensure github.com/boltdb/bolt is installed either via go get or in your vendor dir.
  2. execute go build
  3. run the binary

Result

The binary runs fine when build on windows itself or a normal Linux install but produces the following segfault on Bash for Windows:

fatal error: fault
[signal SIGSEGV: segmentation violation code=0x2 addr=0x7f8d2e0c4008 pc=0x4970e9]

Exact same issue for me. Using mmap in wsl seems to be broken.

They fixed part of MMAP's issues in the fall creator update so check if it works now? See the previous bug #658
