SIGSEGV Sometimes When Closing a Program by Clicking a Button #1604

justdan96 · 2020-11-25T09:59:43Z

Describe the bug:

I've noticed that sometimes my program faults with "[signal SIGSEGV: segmentation violation code=0x1 addr=0xf8 pc=0x7fdae2aa6fc4]". It doesn't happen every time, though, so I'm not sure exactly where it is going wrong, full error is here: https://hastebin.com/efiyuxofag.go

To Reproduce:

Steps to reproduce the behaviour:

Run any Fyne program on my system which closes the window by clicking a button widget, it will sometimes need to be ran lots of times until I can reproduce the exact error message.

Example Code

package main

import (
	"fyne.io/fyne/app"
	"fyne.io/fyne/container"
	"fyne.io/fyne/layout"
	"fyne.io/fyne/widget"
	"fmt"
)


func showConfirm(title, question string, callback func(bool)) {
	a := app.New()
	w := a.NewWindow(title)
	yes := widget.NewButton("Yes", func() {
		callback(true)
		w.Close()
	})
	yes.Importance = widget.HighImportance
	w.SetContent(container.NewVBox(
		widget.NewLabel(question),
		container.NewHBox(layout.NewSpacer(),
			widget.NewButton("No", func() {
				callback(false)
				w.Close()
			}), yes,
			layout.NewSpacer())))
	w.ShowAndRun()
}

func main() {
	showConfirm("MyTitle", "Are you sure?", func(b bool) {
		if b {
			fmt.Println("Confirmed")
		}
	})
}

Device (please complete the following information):

OS: Ubuntu Linux
Version: 20.04
Go version: 1.12.1
Fyne version: 0ca05dc

I've seen something similar, tho this was triggered when I clicked the window close button:

With this piece of code I can reliably reproduce the crash on my machine.
It seems like it's tied to the number of widgets to keep track of, because it worked perfectly fyne without those 50 buttons inside.

package main

import (
    "fyne.io/fyne/v2"
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/container"
    "fyne.io/fyne/v2/widget"
    "strconv"
)

func NewWindow(a fyne.App) {
    w := a.NewWindow("I await deaths sweet kiss...")

    hello := widget.NewLabel("Kill me!")
    cont := container.NewVBox()
    w.SetContent(container.NewBorder(
        hello,
        widget.NewButton("Kill!", func() {
            w.Close()
        }),
        nil,
        nil,
        container.NewVScroll(cont,),
    ))
    for i := 0; i < 50; i++ {
        cont.Add(widget.NewButton(strconv.Itoa(i),func(){}))
    }
    w.Show()
}

func main() {
    a := app.New()
    w := a.NewWindow("Hello")

    hello := widget.NewLabel("Hello Fyne!")
    w.SetContent(container.NewVBox(
        hello,
        widget.NewButton("Hi!", func() {
            NewWindow(a)
        }),
    ))

    w.ShowAndRun()
}
