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

    I found a case where a particle system can become corrupted in a way that causes this warning to spew every frame. I submitted a bug with very simple project where the problem happens 100% of the time, so hopefully that will help. Will update with the tracking number when it shows up on issue tracker. (no trees involved in this case)

    Note: this is not just in win32 builds, any windows build (win64 confirmed)

    I really don't get why Unity gives a 2017 beta prio over outstanding issues on the stable builds, they seem to greatly underestimate the impact of this bug.

    This really hurts our performance and makes the output logs unreadable.

    We have this bug in 5.6.1p1 with no trees in our scene.
