affected/package: go在调用由go编译的dll出现bug

[Linkangyis]

What version of Go are you using (go version)?

支持CGO的任意版本
go version go1.19 windows/amd64

Does this issue reproduce with the latest release?

在任意版本都出现

What operating system and processor architecture are you using (go env)?

go env Output

$ go env
set GOARCH=amd64

What did you do?

我使用了CGO调用把go编译成了dll再由go进行调用

main.go:
package main

import (
    "syscall"
    "fmt"
)

func main(){
    dll := syscall.NewLazyDLL("test.dll")
    jiafa := dll.NewProc("Test")
    demo,err,msg := jiafa.Call()
    fmt.Println(demo)
    fmt.Println(err)
    fmt.Println(msg)
}

Test.dll go:
package main

import("fmt")

import "C"

//export Test
func Test(){
	fmt.Println("Value")
}

func main(){}

What did you expect to see?

正常使用dll

What did you see instead?

初步猜测是因为dll里面用到了接口，导致内存溢出

[ZekeLu]

See #53969 (comment)

[hopehook]

Closing as a dup of #38692. Thanks.

[Linkangyis]

以 #38692 的 dup 结尾。谢谢。

可我是Windows

[hopehook]

The Go shared library that is opened by a program written in C (or C++ or some other non-Go language).

[Linkangyis]

由用 C 语言（或C++或其他非 Go 语言）编写的程序打开的 Go 共享库。

我是由go调用go编译的动态库

[hopehook]

Go cannot call Go DLLs. As @ZekeLu mentioned comments pointed out.

For more details, see issue #38692.

[cuiweixie]

do this with go plugin may be a good choice.

[Linkangyis]

使用go插件执行此操作可能是一个不错的选择

plugin库只能在linux unix使用
