I have managed to get the project built and run with IL2CPP turned on. But only if “split binary” is not enabled. Is this a known issue?

Just wanted to bump this as I am still unable to get IL2CPP working if “Split Binary” is checked on. Otherwise it works perfectly. The logcat of the crash is here:

I got mine to build, but regardless, mine gets a SIGSEGV… 
Likewise, I’m having a similar problem.
EDIT: Oops! forgot to state that mine wasn’t split OBB!!!
What Unity version? We did an OBB fix for IL2CPP in 5.2.1p3.
Yes it’s now fixed. Thank you.
Are we recommended to use IL2CPP for Android or is it safer to stick with mono. What’s the advantages?
From what I’ve gathered, IL2CPP uses native code of which is a lot faster than dalvik code.
The disadvantages are mostly because the support for android is so young… For me, it’s crashes on loading any scene… (well, the first one loads, but any more past that gets a SIGSEGV in the console!) For other people, it’s different problems. In either case, for a serious project, I recommend sticking to mono 2x for now until everything’s fixed up. (5.2.3 might fix some things to do with IL2CPP android, would have to check the release notes)
Is it possible for you to submit a bug report for this crash? The IL2CPP scripting backend should not cause a crash, asn we would like to track down the cause and correct it.
@JoshPeterson I believe we already have an open bug report on @FuzzyQuills problem.
@FuzzyQuills , @VNL-Entertainment-Games most people actually report that IL2CPP is working fine on Android now. There are still some issues but for the majority of projects it should work.
Thanks for letting me know, I was not aware.
I presume it’s the one I sent a few weeks back from the bug reporter… 
Either way, thanks for this. 
I haven’t tried using latest unity yet, but I may as well check it out if it’s apparently fixed up unintentionally.
Also, unless you can’t share that here, what have you found so far in my bug report?
EDIT: I also had an idea… going to test it and report back.
Ok, my test results with IL2CPP…
Attempt to play a movie file with handheld API (In case that was causing SIGSEGV): Works.
Attempt to load a different scene (Application.LoadLevel()): this came up in logcat:
(Check IL2CPP crash.txt, it kept screwing up when pasting into a code window here… :()
Attempt to load using LoadLevelAsync: Same result
This was all done in the most minimalist scene possible, i.e. empty scene with skybox and camera.I did the loadlevel test by directly reloading the first scene.
This is the exact behavior that my working project does when switched to IL2CPP.
To Unity Tech Developers: you probably have a similar log in my bug report already, but in case you need it, attachment’s there to look at.

Thanks which Unity Version are you referring to that IL2CPP is working well now?
Slightly off topic, any chance that the c++ code could not retain original class and method names? I recall still see lots of references of original class/reference names in assembly dump.
I would recommend trying the latest 5.2 patch release for Android, it should have all of the latest fixes.
any chance that the c++ code could not retain original class and method names?
Yes, this is possible. The WebGL platform does this for non-development builds. The Android platform does not does this, but it is possible to expose it as an option. I’m curious though, what is the reason for this request?
There are some players who like to reverse engineer the game. When it comes to IL2CPP they can do it with tools like IDA to easily find human readable functions names, strings etc, modify it and make it unfair for other players of the game. If there are no longer human readable functions/classes/strings etc, it will be much harder to simply find a function like “getHealth” etc and do trial and error value modding. Instead of going straight to “getHealth” they’d have to try a million other methods and hope to get lucky to get anything done. Right now it’s too easy. It’s not going to stop someone very determined, but it will deter the average enthusiasts.
Please report your bugs/crashes on il2cpp - this is the way to get it fully supported and not experimental!
@FuzzyQuills : did you already file a bug? Which case #? I think I’ve seen this crash in one bug report previously - which device did you use?
@VNL-Entertainment-Games : we don’t strip symbols from il2cpp for Android while it is experimental, to easily track down crashes. Once we make it fully supported, the symbols will be stripped, and you should not be able to find function by its name.

Thank you. That makes sense.
Is there a way we can strip them now if we want to (external tool?)
