[Xcode 11] [iOS 13] EXC_BAD_ACCESS in fishhook.c

[chrisspankroy]

Bug

When running my app on an iPhone XR (iOS 13), the app immediately crashes with EXC_BAD_ACCESS.

I can only reproduce this when running on a physical iPhone. iPad and simulator both work fine.

Steps To Reproduce

Make a new React Native project with react-native init and run on device.

Describe what you expected to happen:

1. App to not crash immediately

Reproducible sample code

Here That's a link to a repo I just made for a test project.

EDIT: Fixed the link to the repo

I found a temporary (and terrible) workaround of simply commenting that line out 🙃

However, once it actually runs, a (dismissible) error comes up. This same error occurs in the simulator, although the simulator is not affected by the bad access issue.

[chrisspankroy]

What version of React Native are you using? There was a similar issue ( #25138 ) that was fixed in 59.9. I'm using 59.9 and after commenting out the line in fishhook.c, I can get the app to run fine. But, I'm willing to bet that's not the right solution 😕

[chrisspankroy]

I might have a real fix for it. PR coming soon

[ryanoconnor7]

Got it, thanks. Hopefully that fixes it. Sorry for asking this here but what should I do if I'm using expo and need to upgrade to 59.9?

[chrisspankroy]

I’ve never used Expo, but my understanding of how it works is it can take about a month after a version of React Native comes out for it to be supported on Expo. The Expo SDK should support 59.9 in a few weeks

[ryanoconnor7]

I’m seriously considering ditching it, haha

this should be fixed by 46bdb41, let me know if it doesn't work for you

[chrisspankroy]

Awesome, thanks!

[mjgallag]

Does anyone understand why this crashes in production when all the references to RCTReconnectingWebSocket are in DevSupport classes? I ask because I'm trying to figure out if there is anything I can possibly do to address this issue from a javascript code push. Shot in the dark but if anyone has any ideas let me know, thanks!

[enaluz]

I'm still getting this bug. Any updates on this? So far, the only fix I can find for this (although it's horrible) is to comment the line out.

@mmmulani

[mmmulani]

upgrade your version of RN, it was fixed months ago

[Mcebrera]

@mmmulani What RN version fixed this? I'm on 0.59.10

[mmmulani]

v61.0 I believe is the first to have this fix

[nomoreboredom]

I am also still on 0.59.10, needed to apply these manually to compile 46bdb41

[xeric]

For you guys who are still working on 0.59.10 and hard to apply 46bdb41 patch in to your local.
Go to ‘node_modules/react-native/Libraries/fishhook/fishhook.c' and delete whole method 'perform_rebinding_with_section' content, keep the method definition.
Save -> Done.

I am using

   React Native 0.59.9,
   Xcode 11.2.1(11B500). 
   iOS SDK: iOS 13.2

I tried to reproduce this crash but could not.
It work fine in both simulator and real device(include iPhone XR iOS 13).

I have to decide to update to new React Native version or not.
Do you have any idea why I can not reproduce this crash?

Is it happened only in iOS SDK 13.0 and Xcode 11?

[GleidsonDaniel]

The curious thing is that this error only happens on iphones 11, on inferior devices like X, the error does not happen ...

This still works in 2020

+1 This error occurred only on iPhone 11s. Worked on all other devices including emulators.

v61.0 I believe is the first to have this fix

Oof that sucks because one of our dependencies max supported version as of now is 0.59.9
