Memory leak warnings are thrown when creating a Particle System GameObject
Steps to reproduce:
- Create a new Unity project using the Universal 3D template
- Create a new Particle System (GameObject > Effects > Particle System)
- Observe the Console window
Actual results: Memory leak warnings are thrown
Expected results: No warnings or errors thrown
Reproducible with versions: 6000.0.58f1, 6000.1.15f1, 6000.1.16f1, 6000.2.0f1, 6000.3.0a4
Not reproducible with versions: 6000.0.54f1, 6000.1.14f1
Tested on (OS): Windows 11, macOS Silicon Sequoia 15.5
Notes:
- Also reproduces in HDRP
- Sometimes need to wait a bit after creating the Particle System for memory leak warnings to appear or click on other GameObjects

I get a ton of these showing in a game build with 6.2 .2f1 and seems to be caused by particles, if no particle used no errors...
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.
