Realm-java: Synced Realm crashes with "Fatal signal 11 (SIGSEGV), code 1, fault addr 0xe0" during the first launch

[tejas-n]

Goal

The app shouldn't crash

Actual Results

The app is crashing with

06-26 11:22:42.579 A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0xe0 in tid 11115 (Thread-525)

Steps & Code to Reproduce

This is usually happening when the realm is created for the first time. Sometimes we don't have any issues but sometimes it crashes on the first run(when there is no realm). I can see that the realm is created successfully using Realm Studio.
If it doesn't crash on the first run, it works flawlessly.

[cmelchior]

Hmm, it looks like an issue with a nullpoiinter instead of a C++ object given fault addr 0xe0.

There should also be a native stacktrace. Are you able to post that?

[tejas-n]

Thanks for the reply, @cmelchior.
Do you think this is useful?

Is this problem solved？My app has also encountered this problem.

[rorbech]

We recently realased 7.0.2 containing a memory mapping management fix. I cannot see immediate indications from the traces that it should be exactly this, but maybe try to see if you can reproduct with 7.0.2.

Hi, @rorbech
Unfortunately crash also reproduced after updating from 6.1.0 to 7.0.2:
Tested on Xiaomi MI A3 (Android 10).
I think in my case place of crash is here - mRealm.executeTransaction { realm -> realm.delete(TargetClass::class.java) }

Which does seem to point to a problem with queries...

@cmelchior
Maybe. But on versions <7.x.x crashes don't received. I don't see in logs stacktrace for it (only info provided above). App just crashed after secondary call findAll and etc. Steps: call realm.delete(clazz) - save data (in many places) - findAll (in many places). At the secondary call of this chain - app crashed.

[cmelchior]

It was mostly an internal note. Realm shouldn't crash like this, no matter what. So it is a bug on our end. Unfortunately, these kinds of bugs are really tricky to track down unless we can find a way to reproduce it.

[edualonso]

We have just released version 7.0.3 which includes more fixes regarding memory management. Please upgrade your dependencies and let us know if the problem is still present.

[tejas-n]

@edualonso Thanks, will give it a try.

[tejas-n]

Unfortunately, it crashed again with v7.0.3. I think it crashed before authentication and after the app restarted it was working fine

[VicMikhailau]

@edualonso on 7.0.3 crash also reproduced.

[clementetb]

@VicMikhailau would you mind trying with version 7.0.4, we just released it today and it addresses further memory issues.

[VicMikhailau]

@clementetb on 7.0.5 crash also reproduced.

[clementetb]

@VicMikhailau I am sorry to hear that. Are you able to reproduce this issue your self? Could you please share the steps it takes to reproduce the issue?

[VicMikhailau]

@clementetb
Unfortunately, I can't provide the live production code.
But here are the sequential steps:
Note: for all screens created its own Realm instance.
All screens used the same data from TargetClass.

1. On the Main screen called
   Clear data: mRealm.executeTransaction { realm -> realm.delete(TargetClass::class.java) }

2. Next, for each of the several (4) screens, call:
   a) Save data retrieved from API: mRealm.executeTransaction { realm -> realm.insertOrUpdate(listOf(TargetClass)) }
   b) Retrieve data from Data Base: mRealm.where(TargetClass::class.java).equalTo().between().sort().findAll()
   c) Show Realm data on UI.

When you first run these steps, everything is fine. After the second - crash (received only logs described above).

Crash disappeared when:

• Delete first step
• Or on second step use Realm.getDefaultInstance().copyFromRealm(data from second step)

Thanks.

[sokarcreative]

I have the exact same issue "A/libc: Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)" when upgrading Realm from 5.14.0 to 7.0.5. Everything was fine until I see a crash at a specific step in a transaction.

it seems to be related to RealmQuery<E>.isNull("fieldName") where fieldName is an optional RealmObject

I'm using right now 7.0.6 and I have always the same issue

Note: I can reproduce this error easily.
I have updated two apps in production without seeing this issue. I just upgraded the lib to use the new freeze function :(

[cmelchior]

@sokarcreative That sounds great. If you have a way to reproduce this we would be very interested in seeing it.

[sokarcreative]

@cmelchior Tell me when you think you solved this issue and I will check if this crash persists.

[sokarcreative]

@cmelchior here is the stack trace, I hope it will help :
Pixel 3 (Android 11), multiple emulators (same results)
Android Studio 4.0.1

[cmelchior]

After looking at the unrolled stacktrace, it looks to be a duplicate of https://github.com/realm/realm-java/issues/7118 of which a fix was merged here https://github.com/realm/realm-core/pull/3935. I'll attempt to get a 7.0.7 release out today which should hopefully fix this.

@cmelchior I will wait for the next release (7.0.7) if you think it solves it

[cmelchior]

Realm Java 7.0.7 was released with a fix for this.

[sokarcreative]

It has been fixed ! Tested right now. On 7.0.6 crash then on 7.0.7 no more crash. 👍
Thanks !

[VicMikhailau]

@cmelchior Unfortunately, for my case, crash is still reproducible. I Will be waiting for the next release and make some fixes on my side.
