[Linux] Unity crashes or freezes when loading an AssetBundle with AssetBundle.LoadFromFile

Linux

-

Reproduction steps:
1. Download the attached zip file: "case_1308947.zip"
2, Extract the project and two AssetBundles: "New Unity Project.zip", "CubeV1.assetbundle", "CubeV2.assetbundle"
3. Open the project and enter the Play Mode
4. Click on the "Open" button and select one of the aforementioned AssetBundles

Expected result: The AssetBundle is loaded and displayed
Actual result: Unity freezes or crashes with a variation of the stack trace below

Example of the stack trace:
#0 0x007f18ae9ba980 in funlockfile
#1 0x007f18ae5f5fb7 in gsignal
#2 0x007f18ae5f7921 in abort
#3 0x007f18ae640967 in __fsetlocking
#4 0x007f18ae6479da in _IO_str_seekoff
#5 0x007f18ae64ef0c in cfree

Reproducible with: 2019.4.25f1, 2020.3.6f1, 2021.1.5f1, 2021.2.0a15
Could not test with: 2018.4 (Due to errors when opening the project)

Notes:
- Not reproducible on macOS or Windows
- Reproducible in Editor and Player with both OpenGL and Vulkan Graphics API and either version of the AssetBundles
- Vulkan Graphics API would earlier result in a different crash stack trace but has now been replaced with this one
- Sometimes the Editor freezes only after entering Play Mode the second time and attempting to load an AssetBundle again
- This crash has been observed and reported by users after importing an Asset from the Asset Store, but no consistent reproduction of such issues have been found
