Summary

• Application crashes with EXC_CRASH (SIGABRT) during CoreCLR startup (coreclr_initialize); XHarness exits with code 80.
• Failures occur on tvOS devices run via mlaunch/XHarness in build_tvos_arm64_Release_AllSubsets_CoreCLR_RuntimeTests; no test results produced.
• Crash reports consistently show a kernel VM allocation failure: mach_vm_allocate_kernel failed within vm_map_enter (ktriage arg=0x3).
• Device-side file retrieval failures observed when collecting results (e.g., 'Failed to retrieve file node', CoreDeviceError 7000 copying test-results.xml), indicating crash before results were written.

Failure Statistics

Note: These statistics are based on the configured time range and might not reflect the full history of the failure.

• Occurrence Count: 12
• First Failure: 2026-01-19 01:01:59 UTC
• Last Failure: 2026-01-21 03:02:39 UTC
