Context

This failure has reproduced consistently in the last two gcstress composite builds on windows-x64. It does not appear in the runtime pipeline or other crossgen2 configurations. The Regression_o_2 directory contains tests under src/tests/JIT/Regression/ — the specific test is Regression_o_2.0.1.

Recommended Action

This failure requires deeper investigation as GCStress failures can be complex. Please disable the failing test by adding an [ActiveIssue] attribute referencing this issue. Locate the test project under src/tests/JIT/Regression/ for the Regression_o_2.0.1 work item and add [ActiveIssue("https://github.com/jtschuster/runtime/issues/ISSUE_NUMBER")] to the failing test class or method. The disable should target the GCStress composite configuration specifically if possible.
