crash in bridge code with some native module.

[omatrot]

🐛 Bug Report

Crash in bridge code in Release build only. Works in Debug

void RCTNativeModule::invoke(unsigned int methodId, folly::dynamic &&params, int callId) {
  // capture by weak pointer so that we can safely use these variables in a callback
  __weak RCTBridge *weakBridge = m_bridge;
  __weak RCTModuleData *weakModuleData = m_moduleData;
  // The BatchedBridge version of this buckets all the callbacks by thread, and
  // queues one block on each.  This is much simpler; we'll see how it goes and
  // iterate.
  dispatch_block_t block = [weakBridge, weakModuleData, methodId, params=std::move(params), callId] {
    #ifdef WITH_FBSYSTRACE
    if (callId != -1) {
      fbsystrace_end_async_flow(TRACE_TAG_REACT_APPS, "native", callId);
    }
    #endif
    invokeInner(weakBridge, weakModuleData, methodId, std::move(params));
  };

  if (m_bridge.valid) {
    dispatch_queue_t queue = m_moduleData.methodQueue;
    if (queue == RCTJSThread) {
      block();
    } else if (queue) {
      dispatch_async(queue, block); <----- com.facebook.react.JavaScript (8): EXC_BAD_ACCESS (code=2, address=0x1c20a79b8)
    }
  } else {
    RCTLogWarn(@"Attempted to invoke `%u` (method ID) on `%@` (NativeModule name) with an invalid bridge.",
               methodId, m_moduleData.name);
  }
}

To Reproduce

I'm using several native modules so, deciding which one is faulty is complicated for me.
I'm using Cocoapods, following is my pod file:

platform :ios, '9.0'
	
use_frameworks!
	
target 'MyTarget' do
    pod 'yoga', path: '../node_modules/react-native/ReactCommon/yoga/'
    pod 'React', path: '../node_modules/react-native/', :subspecs => [
    'Core',
    'ART',
    'RCTActionSheet',
    'RCTAnimation',
    'RCTLinkingIOS',
    'RCTGeolocation',
    'RCTImage',
    'RCTNetwork',
    'RCTText',
    'RCTVibration',
    'RCTWebSocket',
    'DevSupport',
    'CxxBridge',
    ]
    
    pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
    pod 'glog', :podspec => '../node_modules/react-native/third-party-podspecs/glog.podspec'
    pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'
    
    pod 'RNCharts', :path => '../node_modules/react-native-charts-wrapper'
    pod 'RNSVG', :path => '../node_modules/react-native-svg'

end
	
swift4 = ['Charts']

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if swift4.include?(target.name)
        config.build_settings['SWIFT_VERSION'] = '4.1'
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= []
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'DEBUG=1'
      end
    end
  end
end

An the result of the install:

[react-native-bot]

It looks like you are using an older version of React Native. Please update to the latest release, v0.58 and verify if the issue still exists.

The "Resolution: Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

[hramos]

Can you provide a minimal reproduction? I don’t see this issue reaching a resolution without one. As it happens, debugging individual crashes in any given project falls out of scope for this issue tracker.

[omatrot]

@hramos I can provide you my repo privately. This is the best I can do right now. Please give me instructions on how to do that.

[aleclarson]

Does it crash every time in Release mode? Does your code ever invalidate the bridge explicitly?

Remove any business logic so you can share the repo.

[omatrot]

Yes No I’ll do that. Stay tuned.

Here is the repo for you to check the issue.

recently upgraded the repo to 0.59.0.
Same issue.

Hi @omatrot thanks for the issue report. I've downloaded your reproduction zip and I'm not finding it easy to pinpoint the issue from there. There is a large set of dependencies and library code in the project. To find the issue, I suggest you start stripping the project of dependencies and code piece by piece, until the issue stops. The last piece you removed is the one causing the issue. When you find it, you can post an issue on the repository of that library where the maintainers will be able to help you.

If the issue turns out to actually be related to RN core, feel free to post the minimal repro showing this and I'll gladly reopen the issue.

[zim-lee]

@omatrot did you fix it? I have the same issue. only crash in Release Mode.

[frapsMatheus]

I'm having the same issue also. Xcode 10.3. Swift 4.2.

Package.json
On debug it works and on Release it crashs in the same place if I click on anything on the screen

[omatrot]

Is solved this problem (and many others) by manually installing native modules and not relying on CocoaPods anymore.
