Unity leaks memory when doing assertion with interpolated string when Burst compilation is off and Profiler is recording
How to reproduce:
1. Open the "burst_leak.zip" project
2. Open the "SampleScene.unity" scene
3. Make sure Profiler is recording and Burst Compilation is turned off
4. Press Play
5. Check Unity RAM usage
Actual result: Unity RAM usage goes up and doesn't get cleaned.
Expected result: Unity doesn't leak RAM.
Reproducible with: 2019.3.0a10, 2019.2.0b10, 2019.1.10f1, 2018.4.4f1, 2018.2.0b6.
Not reproducible with: 2018.2.0b5, 2018.1.9f2.
Notes:
The leak doesn't happen if "Assert.IsTrue(width > 0, $"FAILED: width ({width}) > 0");" MyBurst2Behavior.cs: 51 is commented out.
For the leak to reproduce there are several circumstances combined:
Assertion message is defined as an interpolated string ($ character).
Burst Compilation is turned off (Jobs > Burst > Enable Compilation).
Profiler has to be recording.
In Unity 2018.2.0b1 - 2018.2.0b5 the RAM usage goes up but gets cleaned quickly.
