EXC_BAD_ACCESS on Expo React Native 0.64 iOS real device

[maciej-lepb]

🐛 Bug Report

In an iOS React Native Expo project upgraded from React Native 0.63 to React Native 0.64 the application crashes with EXC_BAD_ACCESS in Flipper upon generating a certificate signing request.

[mweststrate]

cc @jknoxville does this ring a bell? @maciej-lepb could you provide a reproducible setup?

[maciej-lepb]

@mweststrate will try ASAP, I know it's hard to debug without it, although stripping down our current project may take some time. Either way - I'll do my best. Thanks!

[ma125125t]

Got the same problem.Happened on a generic iOS app.Do you have your own openssl lib in your app?

[ma125125t]

Hi @maciej-lepb ,did you get any progress?

[maciej-lepb]

@FFFang I started working on a stripped-down project to demo the issue. Not finished yet, I'll keep you posted. I guess not much that can be done without a demo project, right? Thanks!

[ma125125t]

@maciej-lepb In my case,it is a conflict problem with OpenSSL.xcframework and libssl.a.I have fixed it.

[RebeccaAouizerats]

@FFFang I would like if you can explain how did you find that you have a conflict? and how did you fixed it? Thanks

[ma125125t]

@RebeccaAouizerats check if there is another libssl lib in you project.If there is ,then strip it to use flipper's openssl.

[RebeccaAouizerats]

@FFFang Thanks you, you helped me to think on another direction. Indeed, I have a dependency, that use a framework, that use openssl. When removing the dependency the problem disappear. I have not yet been able to resolve the issue (also by adding openssl to the pod of the dependecy)

[xclidongbo]

mark. the same error.

[xclidongbo]

mark. the same error.

搞定了? 我也遇到这个问题了. 能否请教下怎么解决的?

@xclidongbo 嗯，flipper用的openssl是最新版本的，如果你项目中本身有openssl，且是年代比较久远的，这两个库是不兼容的。解决方法就是修改podspec来修改依赖，在主项目中指定版本，我的情况，是用'1.0.2.20'版本的'OpenSSL-Universal'。

尝试调低OpenSSL的版本号, 不过没啥用, 改了cache中的podspec文件, 但还是安装高版本的.

用本地podspec.json试下

1.0.2.20

没用... 提示有多个依赖

[!] There are multiple dependencies with different sources for `Flipper-Folly` in `Podfile`:

- Flipper-Folly (from `FlipperProject/Thirds/Flipper-Folly/Flipper-Folly.podspec.json`)
- Flipper-Folly (~> 2.2)

[xclidongbo]

我尝试下把所有的Flipper 都放到本地试试

[zuccha]

I have the same problem.

The app crashes either when:

• The app is already running and then I open Flipper
• Flipper is already open and then I start the app

Sometimes I manage to successfully run Flipper and the app, but it is a rare occasion and it breaks as soon as I restart one of the two.

I'm using React Native 0.63.4. The issue appeared when trying to upgrade Flipper from 0.69 to 0.70 (it manifests even with newer versions).

@xclidongbo

Hi,最后解决了这个问题了吗？

[xclidongbo]

@xclidongbo

Hi,最后解决了这个问题了吗？

没有, 我把flipper 去掉了. 用android调试, ios只用来打包.

[mpatafio]

Same issue here 🙁

[mweststrate]

@lblasa any idea what could go wrong here?

[marcshilling]

I get reports about this crash from my production app. Far and away my most frequent crash report...but as far as I can tell it's happening when the app is in the background...

[YahiaJabeur]

Im facing this issue on react native 0.66.2 on a simulator or device! Any idea how to resolve it without commenting use_flipper!() ?

[ybwdaisy]

Same issue here. React Native 0.63.4. use_flipper!({ 'Flipper' => '0.79.0' })

[petpwiuta]

try to update Flipper to 0.135.0 or 0.136.0

[leejunhui]

@ma125125t 你好，我通过你说的方式进行了尝试，Xcode Run 起来之后真机没有 crash 掉了，但是 Flipper 打开后报了如下的错误:

请问你有遇到过吗

[ybwdaisy]

Same issue here. React Native 0.63.4. use_flipper!({ 'Flipper' => '0.79.0' })

For me, is third-party library NIMSDK cause crashes, just remove it work for me.

[ma125125t]

这是因为idb工具有问题，导致无法建立成功的通信，可以参考 https://github.com/facebook/idb/issues/659 里的解决方案。

[leejunhui]

这是因为idb工具有问题，导致无法建立成功的通信，可以参考 facebook/idb#659 里的解决方案。

按照 issue 里面的指引，手动升级了 fb-idb，但是貌似 Flipper 还是不能识别 iOS 真机😂，安卓的真机没啥问题，看来只能先用着模拟器了

[OneHatRepo]

Seeing this on Expo SDK 45, react-native 0.68.2, iOS simulator. Not seeing it on real device.

[davidascholer]

Thought I would comment so this issue didn't get stale. I just ran into this issue after another developer integrated Flipper into our project. After pod deintegrate, I noticed some packages that had been uninstalled and not reinstalled with pod install. After that, I was having clean builds. Not a permanent solution, but it's what unblocked me. For now, at least 🤞

XCode 14.2 React Native v0.70.2 Tested on 3 devices w the same issue/resolve: Ipad Pro 1st gen -Ipad 16.2 Ipad Mini 5th gen -Ipad 16.2 Iphone 7 - IOS 15.4

[chirag-blueed]

did anyone find a proper fix for this issue?
