Bug Application crash when entering a large number of characters

CeleDko · Nov 9, 2020

Hello everybody! My problem is that when I enter a lot of characters in the input field, my application just crashes! I do not understand what the problem is. I tried to put both standard unity input field and tmp.

Message: Native Crash - Unknown Function (/system/lib/libc.so)
Stack Trace: Unknown Function (/system/lib/libc.so)

The following message comes to the report in Cloud Diagnostic:

What Unity version are using, I think I saw similar bug in the past, and it may have been fixed already.

I am using version Unity 2019.4.13f1
But I have opened the project many times by updating my unity. Do you think this could be related?

Unlikely, could you report a bug please with repro project attached if possible - https://unity3d.com/unity/qa/bug-reporting

I thought this was fixed, maybe it's a different issue.

Thank you

CeleDko · Nov 9, 2020

Ok, I have submitted a bug report

PatientZero · Feb 1, 2021

Im also facing this issue in 2019.4.16f1
Is this fixed or a bug report number where we can track the status?

Toastbyte · Feb 1, 2021

I think one simple workaround is to just limit the amount of characters that the user is able to put into the field. Just write a short script for that.

danUnity · Feb 12, 2021

Limiting the amount of character is not a viable solution, I'm getting the crash even with a small amount of text.
I'm getting the error a lot while editing TextField on my app. I can't even write a tweet without the app crashing.

@Tomas1856 : Any news on that crash? Was a issue ever filled with Unity?

I have also attached the logs of the crash

danUnity · Feb 12, 2021

@CeleDko Mind sharing the link to the Issue you filled? Was there ever a fix for this?

Tomas1856 · Feb 12, 2021

There was a related fix to memory allocators - https://forum.unity.com/threads/android-11-arm64-native-heap-allocator-issues.1047170/

But seeing that you're using Mono ARMv7, it's probably something else in your case, I haven't seen reports related to this issue. If you have one, please copy paste the case number.

danUnity · Feb 13, 2021

After looking more I realized I was having the reported issue where it would crash your app if you had more than 64 characters in your InputField component.

https://issuetracker.unity3d.com/is...4.1760455683.1612291871-1166137185.1599844780

After upgrading the unity project to 2020.2.3f1, I had no crashes after that and the application is much more stable now thanks to that!

Thanks for the quick reply @Tomas1856
