Using DisassemblyDiagnoser in GitHub Actions

[eduherminio]

I attempted to add DisassemblyDiagnoser to a benchmark class and run it in GH Actions default runners and I haven't been successful with Linux and macOS.

Linux

Failed to set up high priority. Make sure you have the right permissions. Message: Permission denied`

After running it with sudo:

Process completed with exit code 139

macOS

(similar to #1499):

// * Diagnostic Output - DisassemblyDiagnoser *
No benchmarks were disassembled

Interestingly, when ran with sudo an asm-md file was created, but an empty one.

https://github.com/lynx-chess/Lynx/actions/runs/5882730576 (with sudo)

Branch where I tried to add the DisassemblyDiagnoser: https://github.com/lynx-chess/Lynx/tree/dotnet/90667

Hi @eduherminio

139 is SIGSEGV, which .NET and BDN version did you use? It looks like #2070 which was solved in .NET 8 and backported to 7: dotnet/runtime#79846

BTW macOS is currently not supported: #1499 (comment)

Hi @eduherminio Eduardo Caceres FTE

139 is SIGSEGV, which .NET and BDN version did you use? It looks like #2070 which was solved in .NET 8 and backported to 7: dotnet/runtime#79846

I faced 139 using .NET SDK 8.0.100-preview.7.23376.3 and BDN 0.13.7 in GH actions default Ubuntu runner.

I just tried locally as well (within WSL) with sdk 7.0.306 and same BDN version, and got the 139 as well

You should select the target benchmark(s). Please, print a number of a benchmark (e.g. `0`) or a contained benchmark caption (e.g. `ArrayCopy`).
If you want to select few, please separate them with space ` ` (e.g. `1 2 3`).
You can also provide the class name in console arguments by using --filter. (e.g. `--filter '*ArrayCopy*'`).
Enter the asterisk `*` to select all.

It's probably dotnet/runtime#90691, let's wait until somebody from the .NET Runtime Team investigates it further.
