Argument Exception on Windows IL2CPP build with Burst & Jobs

My project works properly in the editor and on Mono build, but on IL2CPP build I get the error below in the Player log file.Unity editor says it successfully built and I can play it but Jobs seem not to be working.


ArgumentException: Object contains non-primitive or non-blittable data.

In OnCompleteInitializeJob I do dispose completed jobs and copy NativeArrays to arrays. I thought jobs disposed there has some problems with Burst so I tried removing [BurstCompile] from these jobs but nothing has changed.

I am not sure if this is related, but I also get the warnings in the editor console after I built the project successfully.

Could anyone help me solve this issue?

I use Unity 2019.3.0f9, Burst 1.2.3 and Jobs 0.2.5 preview 20. also tried Burst 1.3.0 preview 3 but not work.

 

I've seen this before it happened when I tried to have a data component with an array in it, do any of your components contain collections arrays/lists etc?

 

Thanks for your replying.

I use MonoBehaviour, not ECS, with Jobs, and in any jobs I do not use arrays except NativeArray, NativeQueue, and NativeList.

I found a NativeArray of a struct which has bool is used in a job. But I think Burst supports bool, though I think it is non-blittable data.

In the function which throws the error some jobs are disposed, and I don't know exactly which job has a problem. I will try to figure out later and show the code here.

 

We found recently that bools sometimes seemingly randomly fail blittable checks with IL2CPP (this was for xbox, but based of this I assume it's windows as well.)

 

As @tertle said, IL2CPP and Burst together may have issues with bools. I always got errors with bool variables.

Changing bool fields to int fields fixed my problem. Thanks!

 

Got the same issue.
Thanks.
