Severity: 3Secondary functionality broken

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.

    FYI: 2017.1.0p5 claims to have fixed this, will take me a few days before I can confirm this.

    Still occurs in 2017.1.0f3 with Timeline and Audio tracks, if the audio asset is inactive when starting the editor.

    Still having this issue in 2017.1.0p4
    It seems to be caused by the audio tracks in Timeline.

    For me, it was caused by a corrupt particle system (thanks XEXYL), specifically one particle system that had the sub-emitter module enabled but not set up. Disabling it fixed the warnings:)
