Fatal signal 11 (SIGSEGV), code 1, fault addr 0x10 in tid 20710 - on LG G5

[andrewpmoore]

We seem to keep getting regular crashes on one of our test devices. Either when calling

    try (Realm realm = Realm.getDefaultInstance()) {
        if (!realm.isInTransaction()) {
            realm.beginTransaction();
        }
        //do things here
    }

we'll get the app never getting past the "begin transaction" line, or sometimes it'll throw the following stack.

It doesn't seem to happen on other devices other than this one.

Hi @andrewpmoore
It looks like a bug in ART. Is it something you can reproduce consistently?

[andrewpmoore]

It's probably happening 30% of the time when logging into the app and trying to start storing user data. It doesn't seem to happen at other points when we are also storing data and starting transactions in a similar way.

Hey - looks like you forgot to add a T:* label - could you please add one? 👍
