New one to me for errors signal 4 SIGILL. When I take a look at the tombstone file and type int he address I get ?? i.e.
Here is someof the tombstone:

I go my android-ndk-r7\toolchains\arm-linux-androideabi-4.4.3\prebuilt\windows\bin directory using command window, type in this command and get no function at all.
arm-linux-androideabi--addr2line.exe -C -f -e libdvm.so 0003a8ce
and it returns
??
??:0
I seem to remember this working before...and yes I have the libdvm.so in the same working directory.
Well apparently this occurs only when I test it on the 2.2 emulator. On a myTouch 3G phone the code never crashes. Must be a pointer memory issue or not enough RAM allocated for simulator.

We're trying to update unity from version 2019 to 2021.
After update android application randomly crashes. Session time from 3 minutes till 40.
Also, there no steps to repo.
Tried to disable all SDKs, update to 2020 and 2022, change stripping code, change compilation from il2cpp to mono and lof of other variants but without any results.
It would be great to hear any ideas. Thx!

We face this issue also but on lower update: from 2021.3.9 to 2021.3.12. It was affecting 20% of our users on production.
According to logs, it is related to scene loading.
So looks like this issue started to appear somewhere after 2021.3.9.
Rolling back to this .9 version solved it for us.

I am using this method to convert the address to code location but the result seems no right. Is there any better way to find the crash code location in my file or unity native code?
I got this crash reported on the play developer console from a Galaxy S4. Any clue what it's about?

Here's the primary error message pulled out from that mess:
Abort message: 'sart/runtime/class_linker.cc:3054] Check failed: dex_cache.Get() != nullptr Failed to allocate dex cache for /data/app/com.google.android.gms-1/base.apk'
There were no user comments so I have no idea how to reproduce it. Is there anything I can do to track this down?
I am running into an issue in my Android app where Galaxy Note 4, Galaxy Edge, and some other devices crash when trying to play H.264 video streamed from a server. I'm fairly certain that the H.264 video is correct, as the same video works using the same decoder on other devices. In addition, the devices that are crashing support the decoder that I'm using.
It doesn't crash in my source code, but it does crash the app. Has anyone ever run into this issue? If so, could you give me some help on what I could do to figure out what is happening? Here's the message I'm getting from the Developer Console in Google Play:

Since no app symbols are in output (no my methods in JNI code) how can i understand what's wrong? Is it missing .so lib that should be loaded before loading libffmpeg.so ?
Look at the address- DEADBAAD. Notice its in english? That means it was set that way purposely (the odds against it are astronomical). In particular its a value used by the JVM to overwrite pointers inside Java references that are no longer valid. So you're passing a value to C code that is no longer valid, or the C code is holding onto a reference without properly telling the VM it's doing so by incrementing its reference count. This can frequently be a result of a race condition if your code is multithreaded.
You can utilize ndk-stack tool provided by Android NDK.
The details can be found from NDK doc:
android-ndk-r10d\docs\Programmers_Guide\html\md_3__key__topics__debugging__n_d_k-_s_t_a_c_k.htm
This tool basically helps you convert the content in the memory into human-readable debug information. Sometimes, it is extremely helpful.
The following is copied from the NDK document:
The tool can convert the following information
