Test Failure: HardwareIntrinsics_X86_ro

[kg]

Summary:

HardwareIntrinsics_X86_ro process exits with code -1 under JitStress2+JitStressRegs on Windows x86, despite all individual tests passing.

Failed in (2):

• runtime-coreclr jitstress2-jitstressregs 20260408.1

• runtime-coreclr jitstressregs 20260408.2

Error Message:

App Exit Code: -1
Expected: 100
Actual: -1
END EXECUTION - FAILED

Stack Trace:

N/A

Analysis:

All individual xunit tests pass but the process exits with -1 during shutdown. Likely a JIT crash during AppDomain teardown under extreme register pressure on x86 (8 GP registers). No crash dump or error output between last passing test and exit code.

Summary:

HardwareIntrinsics_X86_ro test harness crashes with exit code -1 on Windows x86 under jitstressregs2 and jitstress2_jitstressregs2. All individual HW intrinsic tests pass, but the overall process exits with -1.

• runtime-coreclr jitstress2-jitstressregs 20260408.1

Error Message:

Actual: -1
END EXECUTION - FAILED
All individual tests passed but the test harness process crashed with exit code -1 after completing all 628 test reports.

Stack Trace:

N/A

Analysis:

The test runner process crashes after all individual tests complete successfully. The XUnitLogChecker confirms the item completed successfully, but the process still exits with -1. This appears to be a test infrastructure or JIT stress issue rather than a test logic failure.
