Editor freezes when viewing/building asset bundles if a custom font is used in a TextMesh

Asset Bundles


Steps to reproduce:
1. Open the attached project
2. Open the Test_Scene
3. "New Text" GO/Text Mesh component -> change Font to Avenir-Black-03.
4. Save
5. Go to Window/AssetBundle Browser and click the refresh button several times and/or click between the Configure and Build tabs
6. Observe the freeze

Reproducible with 5.6.6f2, 2017.4.3f1, 2018.1.1f1, 2018.2.0b5, 2018.3.0a1 (96cbaa2912e7)

- GO with a TextMesh component is unrelated to the asset bundle and it doesn't need to be nested under the Cube
- Freeze can also be reproduced by calling BuildPipeline.BuildAssetBundles (Build Asset Bundles/Build All Asset Bundles)
- These assertion errors are thrown forever:
Assertion failed on expression: 'm_ActiveBlocks[i].locked == 0'
Assertion failed on expression: 'res'

    I had a similar issue, BuildPipeline.BuildAssetBundles was freezing and after several minutes produced a lot of the same errors.

    I changed my BuildAssetBundles options from BuildAssetBundleOptions.Strict to BuildAssetBundleOptions.None and the problem disappeared.

    Hope it helps
