[Crossgen2 CI] Composite (non-LVB) runtime test failures: jit64_3, Regression_NoOptimize_d, Regression_ro_2

[github-actions]

Failure Details

• Pipeline: runtime-coreclr crossgen2-composite
• Build: 1354390
• Configuration: osx x64, windows x86 / checked (Composite mode, non-LargeVersionBubble)
• Error Category: test-failure

Scope of Failure

9 out of 18 jobs failed in the crossgen2-composite pipeline. Beyond the known TypeMap/Interop failures (dotnet/runtime#125941) and Composite_LargeVersionBubble failures (#16), the following work items fail in standard Composite mode:

Job	Failed Work Items (excluding known Interop)
Composite osx x64 checked	Regression_NoOptimize_d, Regression_ro_2
Composite windows x86 checked	jit64_3
Composite windows x64 checked	(Helix details truncated)
Composite linux x64 checked	(Helix details truncated)

Analysis

The jit64_3 work item fails on both osx x64 and windows x86 Composite mode. Regression_NoOptimize_d and Regression_ro_2 fail on osx x64 Composite mode. These are standard (non-LargeVersionBubble) composite test runs, suggesting the regression affects both LVB and standard composite modes.

This may be related to #16 (Composite_LargeVersionBubble failures) and #12 (R2R_CG2 failures), potentially sharing a common crossgen2 codegen root cause.

Recommended Action

This failure requires deeper investigation:

1. Examine Helix logs (requires auth) for specific test-level failures in jit64_3 and Regression work items
2. Check if the same tests pass in non-composite R2R mode (R2R_CG2) — if they do, the issue is composite-specific
3. Look for recent changes to composite image generation in crossgen2
4. Coordinate with #16 and #12 investigations

Auto-Closed: Not Reproducing

This failure has not reproduced in the last 3 builds on main for the crossgen2-composite pipeline. Regression_NoOptimize_d and Regression_ro_2 have not been seen since early April. The issue has been open for more than 7 days. Closing as no longer reproducing. Reopen if the failure recurs.
