This occurs in runtime-extra-platforms, right?

[kotlarmilos]

Correct, the test is failing on apple mobile platforms.

@kotlarmilos, OK, at some point I would like to investigate why, I have run the underlying gcdump mechanisms on maccatalyst (amd64,arm64), iosSimulator (amd64,arm64), tvosSimulator (amd64, arm64) and Android and we can collect dumps, so not sure why that CI test would fail. Do you know how I can run the specific runtime test on tvosSimulator for example?

[kotlarmilos]

Repro steps:

1. Build the runtime

./build.sh -ci -arch x64 -os tvossimulator  -s mono+libs -c Release

2. Build and AOT compile the tests

./src/tests/build.sh  ci os tvossimulator x64 Release -mono tree tracing/eventpipe /p:ArchiveTests=true /p:DevTeamProvisioning=- /p:RunAOTCompilation=true /p:MonoForceInterpreter=true /p:LibrariesConfiguration=Release

3. Run the app bundle using Xcode using the following environment variables

MONO_APPLE_APP_ENTRY_POINT_LIB_NAME = 'testdir-gcdump/gcdump.dll'
MONO_APPLE_APP_ASSEMBLY_LOAD_PREFIX = 'testdir-gcdump'

Note: You may need to provide a correct path to the cross compiler in the AppleBuild.targets.

@kotlarmilos Do you think you can file an issue and assign it to me that we have disabled the test on Apple Mobile platforms? Just to make sure we don't forget to fix it at some future point in time?
