[ci-scan] Apple NativeAOT test harness crash: mono_ios_set_summary requires marshalling not yet supported by ILC #130219

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1493986
Build error leg or test failing: tvos-arm64 Release AllSubsets_NativeAOT - System.Console.Tests (every library test assembly on this leg fails identically)

Error Details

The Apple NativeAOT test harness (SimpleTestRunner in src/libraries/Common/tests/AppleTestRunner/AppleTestRunner.cs) aborts on startup before any test runs. The mono_ios_set_summary(string) p/invoke cannot be marshalled by the NativeAOT compiler (ILC), so every work item on the tvos-arm64 Release AllSubsets_NativeAOT leg fails with the same unhandled exception (System.Console.Tests, System.Diagnostics.FileVersionInfo.Tests, System.IO.Compression.ZipFile.Tests, System.Net.HttpListener.Tests, System.Net.Ping.Functional.Tests, System.Runtime.Caching.Tests, and the rest of the leg's assemblies).

Unhandled exception.
System.Runtime.InteropServices.MarshalDirectiveException: Method '[System.Console.Tests]SimpleTestRunner.mono_ios_set_summary(string)' requires marshalling that is not yet supported by this compiler.
   at SimpleTestRunner.mono_ios_set_summary(String value)
   at SimpleTestRunner.<Main>d__5.MoveNext() in /_/src/libraries/Common/tests/AppleTestRunner/AppleTestRunner.cs:line 97
   at SimpleTestRunner.<Main>(String[] args)

This surfaced after #125437 (merged 2026-07-02) enabled NativeAOT library tests on Apple mobile in runtime-extra-platforms. It is a stable, reproducing signature: observed on the source build 1493986 and again on the follow-up build 1494308 (Helix job 5f2fd0c4-e5cb-4456-963f-e105fa228f7b) on the same leg. The [System.Console.Tests] assembly qualifier in the message varies per work item, so the signature below omits it and matches all affected assemblies.
