My application crashes without a stack trace after device rotation if it doesn't register for orientation changes in the AndroidManifest.xml. It is only reproducible if the current activity's orientation is set to a value such as android:screenOrientation="landscape" in my case.

<?xml version="1.0" encoding="utf-8"?>
<manifest
  xmlns:android="http://schemas.android.com/apk/res/android"
  package="org.golang.todo.main"
  android:versionCode="1"
  android:versionName="1.0">

  <uses-sdk android:minSdkVersion="9" />
  <application android:label="Drum machine" android:hasCode="false" android:debuggable="true">
  <activity android:name="android.app.NativeActivity"
    android:label="Main"
    android:configChanges="keyboardHidden"
    android:screenOrientation="landscape">
    <meta-data android:name="android.app.lib_name" android:value="drummachine" />
    <intent-filter>
      <action android:name="android.intent.action.MAIN" />
      <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
  </activity>
  </application>
</manifest>

Update: Each Android apk that is built with gomobile crashes. It outputs a log with malloc deadlock. See #10469 (comment).

Not reporting stacktrace is worrisome - hopefully we figure out why there is no log and fix the problem before the freeze if possible. Can you provide a sample app and file a separate issue for it? You can assign the bug to me. Thanks!

I got the crash logs

Tested Nexus5/lollipop and Nexus7/kitkit and they exhibit different types
of logs. malloc deadlock?.

I guess the malloc deadlock is a red herring. The preceding log message may be the more interesting one.

F/libc (12348): Fatal signal 11 (SIGSEGV), code 2, fault addr 0x7af3c000 in tid 12365 (Thread-1452)

Now we are going through many changes in the main and the mobile repositories, let's continue debugging after the dust settles.

FWIW, I'm unable to reproduce the crashes on

  • Nexus 5 Android 5.1
  • Nexus 5 Cyanogenmod 4.4.4
  • HTC One S Android 4.1.1

Running gomobile tip (4e56a5f1a) and Go tip (3115952)

Still reproducible on Nexus 9 - Android 5.0.2 and Nexus 9 - Android 5.1.1.

Is this still reproducible? If it is, the cause seems like a core Go problem and according to

https://groups.google.com/forum/#!topic/golang-dev/fcIhmOnwhK8

the 1.5 beta is close and I would prefer the (possible) fix for this issue not get rejected because of stricter CL standards. I'd happily do the debugging myself, but I don't have access to a Nexus 9.

@rakyll can you check if it's still reproducible on your Nexus 9?

I don't have an Android device with me currently, will give it a try this evening.

We've also seen this happen on ARM with Go 1.5.1, the issue seems unrelated to gomobile.
https://gist.github.com/CJentzsch/31aab5b31fae6805f893

Should we open a new issue about this?
