Description

So, this is going to be tough because I don't have exact reproduction steps for this error. We're getting reports into our Bugsnag application of crashes, which we've experienced ourselves, but as I said, are unable to reproduce.

I've tried going through the stacktraces of the bugs, and a lot of them are consistent amongst themselves but there are also different once as well.

Here are the stracktraces:

Reproduction

No exact reproduction steps that I can explain.

Solution

Figure out where the issues are coming from as the errors don't explain much. Error 3 came from somewhere in main.bundle.js which sounds like a JS related issue but the variable name y doesn't tell me much either and the line numbers are so early on it looks like the react native base code.

Additional Information

  • React Native version: 0.39.0
  • Platform: iOS (
  • Operating System: MacOS

This is very hard to reproduce, and I believe it happens when a view gets unmounted.

An interesting update.. I was working today (using react-redux in my project) and I forgot to connect the component that I was exporting. I literally had:

export default connect(null, { purchase: buyStory })

and not

export default connect(null, { purchase: buyStory })(StoryContainer)

and it threw me a red screen error saying: A valid React element (or null) must be returned. You may have returned undefined, an array or some other invalid object. So, I fixed it and went about my day. Made a few more changes and did some more refreshing. Went to save again, a couple minutes later, and the app crashed. Curious as to why all of sudden it crashed, I checked the Bugsnag reports and saw this:

EXC_BAD_ACCESS Attempted to dereference garbage pointer 0xb9971bec8. 
    Invariant Violation: wrapWithConnect(...): A valid React element (or null) must be returned. You may have returned undefined, an array or some other invalid object.

What's interesting is that this error didn't exist anymore but it still caused the app to crash. I re-built and ran the app (without changing a line of code) and it fired up fine. So the error definitely wasn't there but it was like it cached the error from earlier. Not sure if this provides any insight as to what's going on but wanted to share anyway.

@dwilt Could it just be that the bug report was sent with a delay?
I think the error you saw was dispatched before you fixed it.

The question now is why you got Attempted to dereference garbage pointer.

Either way I believe @kattrali might be able to shed some light on this..!

@SudoPlz It's possible I guess but I doubt it because it errored with the typical red screen first - not crashed. Then it crashedmany builds/runs later and then when I restarted the app, I saw it say "Sending 1 crash report". Anyway, was just working performing my usual behavior in my app that works fine (scrolling a view) when I got this:

@SudoPlz Same issue as you with the ShadowView!

Tried rerunning and oddly Bugnsnag didn't send the crash report either.. (Note the Sending 0 crash reports)

We are seeing a similar error with the whatwg-fetch/fetch.js module. Its the same error more or less:

EXC_BAD_ACCESS in /Volumes/MyProject/node_modules/react-native/node_modules/whatwg-fetch/fetch.js:441 Attempted to dereference garbage pointer 0xabe4ebec8.

Like you - its being caught in bugsnag only. Its very rare when it happens, and we cannot reproduce it. I am posting because I saw you mentioned it was related to a fetch module you are using, and was curious if you were able to discover the root cause.

It‘s rare indeed but still happening at rn version 0.55.0:

EXC_BAD_ACCESS: Attempted to dereference garbage pointer 0x20.
Originated at or in a subcall of folly::Expected<long long, folly::ConversionCode> folly::detail::str_to_integral(folly::Range<char const*>*)

Still observing this sporadically with RN 0.55.3. Usually happens the first time it launches after building from Xcode.

EXC_BAD_ACCESS: Attempted to dereference garbage pointer 0x10ff25f04.
Originated at or in a subcall of -[RCTHTTPRequestHandler sendRequest:withDelegate:]

I am also observing this in production.

I have an app with ~10000 active iOS users over the last month.
Over the same period, bugsnag has recorded 191 events of this type, over 173 users.
These events come from around 50 types of error, with the most common being in _mh_execute_header in CoreGraphics with around 50 events.

If anyone is looking in to this I would be happy to provide more information.

I'm on the same boat @StribMaxMarti are you able to constantly reproduce this?

same here, really annoying.. any updates on this issue? @StribMaxMarti @SudoPlz

I haven't been able to replicate in dev thus far.

Looking at recent occurrences, this seems to be happening after a user opens a specific webpage in my app's "browser" (webview with custom chrome). The error occurs seconds to hours after. My guess is that the browser stays mounted and something about the page causes the crash, perhaps a memory leak.

The url: https://www.mlb.com/cut4/meet-gabby-dimarco-the-fan-who-caught-the-foul-ball-in-her-beer/c-279997458

There are other instances of this error that aren't related to the webview, so this is only part of the picture.
