Internal: JobTempAlloc ... lifespan of 4 frames .. leak - is Debug.log/StackTrace related?

Unity Engine

1

On unity 2022.2.1f - Windows 10.
In editor and Win Builds player log.

The errors appears randomly after some Debug.Log calls … and seems to be related to:
UnityEngine.StackTraceUtility:ExtractStackTrace ()

Deleting the Debug.Log calls or disabling the stacktrace from the log makes most of them disappear.

Is this some internal bug where the stack trace is jobified?
Could someone point me to what exactly is internally managed by the JobSystem in unity? Update calls, StackTrace, coroutines, is there any internal check on pure C# tasks age? (guess they should be indipendent)

Internal: deleting an allocation that is older than its permitted lifetime of 4 frames (age = 11)

UnityEngine.DebugLogHandler:LogFormat (UnityEngine.LogType,UnityEngine.Object,string,object[])
UnityEngine.Logger:Log (UnityEngine.LogType,object)
UnityEngine.Debug:Log (object)

It’s probably related to the Memory that you’re allocating for the String that Debug.Log() is supposed to write out.

Most of the internal checks are related to memory allocation & deallocation

Or the memory the stacktraceutility uses when called by the log. This is with the leak diagnostic on.
Beacause of the Debug.log call and since deleting them makes the error disappear I thought this is some internal stuff related to the StackTraceUtility.
But I can’t fully understand the diagnotic log.

Internal: deleting an allocation that is older than its permitted lifetime of 4 frames (age = 9)
Internal: JobTempAlloc has allocations that are more than the maximum lifespan of 4 frames old - this is not allowed and likely a leak
To Debug, run app with -diag-job-temp-memory-leak-validation cmd line argument. This will output the callstacks of the leaked allocations.
Allocation of 512 bytes at 4056c880 in block 1 (frameIndex=8, lifetime=4, age=4, state=OK)
