JobTempAlloc error appears in Standalone Build output log if trees are in the Scene



Reproduction Steps:
1. Import attached project.
2. Open Test scene.
3. Build and Run.
4. In Standalone Build Data files, open output.log.

Expected result: Allocator errors should not be shown.
Actual result: The following error appears:
"Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak"

Note #1: If trees are removed from terrain, the error no longer appears.
Note #2: No obvious memory leak is detected.

Reproducible with: 5.5.3f1, 5.6.0f3, 2017.1.0p2

    the solution: go to directional light _ shadow type_ turn on to no shadow

    For this is happening when I play Timelines (Playable Director) and seems to hurt the performance.

    2019.1.0b6 - issue is caused by enabling shadows on the directional light. Disabling shadows stops this error from logging out. Not acceptable.

    Version 2018.3.0f2 this error occurred and resolved upon resetting unity. Have not been able to recreate it.
