I build the code with the -race flag on window 7 x64 ,when I run it ,windows popup a dialog indicate that the exe is stopped,and there is no other information display in the console
if I build the code without -race flag,ererything is fine.
go: is 1.3.3 x64
code shows as below:
package main
import (
"database/sql"
"fmt"
)
func main() {
db, err := sql.Open("sqlite3", "./test.db")
if err != nil {
fmt.Println("err%+v", err)
return
}
defer db.Close()
err = db.Ping()
if err != nil {
panic(err.Error())
}
fmt.Println("ok")
}

There were improvements made in Go runtime on "information display in the console" front recently. If you do your exercise on the tip, you will get stack trace instead. Like that:
C:\go\path\src\t>foo.exe

Before I add the sqlite3 package to my project,everything is fine and go build -race works well too. But after I add the sqlite3 ,the exe which build by -race flag can't run correctly
So I start a new project with only sqlite3 package,the exe build with -race flag also run uncorrectly.The new project code is post in the email
