MSB6006: "csc.dll" exited with code 143

[vpapidokha]

Summary of the issue:
Randomly getting the error during CI process, but don't see any kind of regularity. As much as we don't see detailed information about problem neither in the log output nor on the internet.

Log from build process:

13:55:33 /usr/share/dotnet/sdk/5.0.100/Roslyn/Microsoft.CSharp.Core.targets(71,5): error MSB6006: "csc.dll" exited with code 143. [/var/lib/jenkins/workspace/*.csproj]
13:55:33 MSBUILD : error MSB4166: Child node "2" exited prematurely. Shutting down. Diagnostic information may be found in files in "/tmp/" and will be named MSBuild_*.failure.txt. This location can be changed by setting the MSBUILDDEBUGPATH environment variable to a different directory.
13:55:33 /usr/share/dotnet/sdk/5.0.100/Roslyn/Microsoft.CSharp.Core.targets(71,5): warning MSB5021: Terminating the task executable "dotnet" and its child processes because the build was canceled. [/var/lib/jenkins/workspace/*.csproj]
13:55:33 /usr/share/dotnet/sdk/5.0.100/Roslyn/Microsoft.CSharp.Core.targets(71,5): error MSB4181: The "Csc" task returned false but did not log an error. [/var/lib/jenkins/workspace/*.csproj]

The mentioned in the log output file MSBuild_*.failure.txt is absent. We have several in our /tmp directory, but the time of their creation is significantly differentiate. However, I see a bunch of files that have relevant time stamps, but didn't find any helpful info about them.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Had a chat with Jared. Suggested this was/is likely runtime related since there's no stack trace

Since this issue is two years old. @vpapidokha, does this continue to repro for you?
