Leak Detected on Jobs

#1

I’ve a lot of leaks. Using 4.3.94, but I don’t know from which version they started to appear (they’ve been around for a while).
I’ll post all different ones:

Found 1 leak(s) from callstack:

Hi

Can you consistently replicate this leak?

#3

I get the Found 257 leak(s) from callstack: only when using RVO Simulator (obviously).
Do you mean if I can get you a minimal code with these leaks?

#4

Thanks!
I’ve managed to replicate this now. I will include a fix in the next update.

Sorry, still there with 4.3.95 :frowning:

Weird… If you have a test project in which you can replicate this, I would be very interested.

#7

Here a prj.
I think that the problem is the URP stuff
the leak happen at the second+ run of SampleScene

Ok, I’m 100% sure Unity’s NativeQueue has a bug. I can replicate this leak, but only when burst is enabled. And I verify that I am allocating a queue exactly the same number of times as I am disposing it. So something’s off.

I’ll switch it out to my own queue implementation for the next release (which is probably faster too).
