Summary

Multiple Helix work items fail on maccatalyst CoreCLR Release (both x64 and arm64) and tvos-arm64 CoreCLR Release. Work items crash without producing individual test results.

15 work item entries affected across 3 legs (7 unique work items):

• Microsoft.Extensions.DependencyInjection.ExternalContainers.Tests
• Microsoft.Extensions.Hosting.Unit.Tests
• System.Diagnostics.TraceSource.Config.Tests
• System.Reflection.Emit.ILGeneration.Tests
• System.Reflection.Emit.Tests
• System.Reflection.Metadata.Tests
• System.Security.Cryptography.Tests

Note: This issue uses timeline ErrorPattern matching because Helix console logs for this build expired. Once a fresh build reproduces this failure, update with specific error text from the Helix console log and set ExcludeConsoleLog to false.

Note

This issue was filed with the assistance of GitHub Copilot.
