What did you do?

Built an Android app that includes a go module compiled with

gomobile bind -x -a -glflags="-mod=readonly" -ldflags="-s -w" -target android -androidapi 21 .

And included it with a build.gradle dependency:

dependencies {
    [...]
    implementation project(path: ':myGoModule')
}

using

    compileSdk 34
    minSdkVersion 21
    targetSdkVersion 34

What did you see happen?

Since our last upgrade to go1.23, the compiled Android app crashes at startup on older Android versions (tested 9.0 and 10.0, i.e. API 28 and 29 on Android studio emulator) with the following error:

2024-11-21 15:13:36.524 17389-17472 GoLog                   ch.shiftcrypto.bitboxapp.debug       E  [WARNING:viz_main_impl.cc(85)] VizNullHypothesis is disabled (not a warning)

Everything works fine for newer Android versions (e.g. 13.0).

Upgrading to Go 1.23.3 doesn't solve the issue, but reverting to Go 1.22.4 does, on all the Android versions tested.

What did you expect to see?

The app should not crash on startup.

I have no idea. Isn't this a compiler issue?
