[ci-scan] Test failure: System.Transactions.Tests.AsyncTransactionScopeTests.AsyncTSTest

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1489260
Build error leg or test failing: windows-x64 Release libraries JitStress (Helix queue windows.10.amd64.open.rt) — System.Transactions.Tests.AsyncTransactionScopeTests.AsyncTSTest
Pipeline: runtime-coreclr libraries-jitstress (AzDO definition 138) on main.

Error Details

Under the libraries-jitstress configuration the async transaction-scope test fails in its RemoteExecutor child process with an unhandled System.Exception: Test failed with events: raised from AssertTransaction:

System.Transactions.Tests.AsyncTransactionScopeTests.AsyncTSTest(variation: 54) [FAIL]
  Microsoft.DotNet.RemoteExecutor.RemoteExecutionException : Remote process failed with an unhandled exception.
  Stack Trace:
    Child exception:
      System.Exception: Test failed with events:
      ...
      at System.Transactions.Tests.AsyncTransactionScopeTests.AssertTransaction(String txId) in /_/src/libraries/System.Transactions.Local/tests/AsyncTransactionScopeTests.cs:line 1669

Seen in build 1489260 (finished 2026-07-01) and still present in the later build 1491202, so this is not a one-off flake.

Linked KBE: #130126

Root-cause analysis (read-only hand-off)

Under the JIT-stress libraries configuration (runtime-coreclr libraries-jitstress, AzDO definition 138) System.Transactions.Tests.AsyncTransactionScopeTests.AsyncTSTest(variation: 54) fails inside its RemoteExecutor child process:

Microsoft.DotNet.RemoteExecutor.RemoteExecutionException : Remote process failed with an unhandled exception.
  Child exception:
    System.Exception: Test failed with events:
    ...
    at System.Transactions.Tests.AsyncTransactionScopeTests.AssertTransaction(String txId)
      in /_/src/libraries/System.Transactions.Local/tests/AsyncTransactionScopeTests.cs:line 1669

The failure appears only under the JIT-stress configuration and reproduces across builds (1489260 and 1491202), so it is a stable stress failure, not a flake. An async/await transaction-scope flow that is correct under the default JIT but wrong under JIT stress points to a JIT stress-mode codegen issue in the async state machine / transaction-ambient-flow, rather than a defect in the transactions library or the test.

Per this workflow's rules, JIT codegen fixes (and codegen-stress workarounds in library/test code) are out of bounds for an automated PR, so this is a hand-off.

Evidence

Failing build: 1489260 (leg windows-x64 Release libraries JitStress, Helix windows.10.amd64.open.rt), still failing in 1491202.
Affected pipeline: runtime-coreclr libraries-jitstress (def 138) on main.

Note

This root-cause hand-off was generated by an AI/Copilot agent (ci-failure-fix). No code change was produced because the evidence points to JIT-stress codegen that must not be worked around in library or test code. Please verify before acting.

@VSadov

@VSadov the assert was added in #129502. Can you take a look?

I couldn't find anything that stores ManagedThreadId.t_currentManagedThreadId in CoreCLR. Where is that expected to happen?

Ah, looks like the TLS field has special allocation here:

runtime/src/coreclr/vm/threadstatics.cpp

Lines 728 to 732 in 1d85f40

    
           else if (pMT == CoreLibBinder::GetExistingClass(CLASS__THREADID)) 
        
           { 
        
               newTLSIndex = TLSIndex(TLSIndexType::DirectOnThreadLocalData, offsetof(ThreadLocalData, managedThreadId) - OFFSETOF__CORINFO_Array__data); 
        
               usedDirectOnThreadLocalDataPath = true; 
        
           }

I looked at the dump and this looks like the same underlying issue as #130212. So this was already fixed by #130317.

@jakobbotsch

@jakobbotsch, it failed on 7/11.

Failed in (1):

runtime-coreclr libraries-jitstress-random 20260711.1

Console Log: Console Log
Source: runtime-coreclr libraries-jitstress-random / net11.0-linux-Release-x64-jitstress_random_2-AzureLinux.3.Amd64.Open / System.Transactions.Tests.AsyncTransactionScopeTests.AsyncTSTest

Failed tests:

- net11.0-linux-Release-x64-jitstress_random_2-AzureLinux.3.Amd64.Open
- net11.0-windows-Release-x86-jitstress_random_1-Windows.10.Amd64.Open
  - System.Transactions.Tests.AsyncTransactionScopeTests.AsyncTSTest

This was a duplicate of #130212 so it should be fixed by #130536 too.

Indeed, I don't see it in the latest run of libraries-jitstress.
