Command Line Argument -RunTests Fails with 'm_LastAlloc == NULL' on Unity 2020.3.1f1

Unity Engine
1

I’m starting this thread because our build system is running into issues with building TestRunner executables. We are using Unity 2020.3.1f1. We are able to build TestRunner builds using the editor UI, as well as the command line args on our Windows and Mac development machines. We, however, are unable to get our ubuntu build machine (more details below) to run the same command line arguments.

Our build machine uses concourse and these are the images we use for the build steps:

Note that the arguments for -buildWindows64Player and -buildOSXUniversalPlayer both work in the same setup and we are currently using that in our continuous deployment pipeline. Only the test runner builds are having this issue.

Here are the end of the logs where you can see Assertion failed on expression: ‘m_LastAlloc == NULL’

To me, this looks like it may be a regression of this: Unity Issue Tracker - Crash Assertion failed on expression: 'm_LastAlloc == NULL' when running URP automated tests with -runTests cmd line option

Any help would be greatly appreciated! Let me know if more specific information is needed.

Same here using Unity 2022.2.12f1 to make a Windows build via github actions.
