Description

When running the latest dotnet SDK with threading events enabled, writing out the ThreadPoolWorkerThreadStart event causes a crash.

Steps:

  1. Build the tip of https://github.com/dotnet/installer. The latest official build does not consume the latest runtime yet.
  2. Start a PerfView session: PerfView.exe collect /ThreadTime
  3. Run dotnet new console

The following is output:

Fatal error. Internal CLR error. (0x80131506)
at System.Diagnostics.Tracing.NativeRuntimeEventSource.ThreadPoolWorkerThreadStart(UInt32, UInt32, UInt16)
at System.Threading.PortableThreadPool+WorkerThread.WorkerThreadStart()
at System.Threading.Thread.StartCallback()

          Description
          When running the latest dotnet SDK with threading events enabled, writing out the ThreadPoolWorkerThreadStart event causes a crash.
          Steps:
          1. Build the tip of https://github.com/dotnet/installer. The latest official build does not consume the latest runtime yet.
          2. Start a PerfView session: PerfView.exe collect /ThreadTime
          3. Run dotnet new console
          The following is output:
          Fatal error. Internal CLR error. (0x80131506)
at System.Diagnostics.Tracing.NativeRuntimeEventSource.ThreadPoolWorkerThreadStart(UInt32, UInt32, UInt16)
at System.Threading.PortableThreadPool+WorkerThread.WorkerThreadStart()
at System.Threading.Thread.StartCallback()

          This is the full stack under a debugger:

                Description
                When running the latest dotnet SDK with threading events enabled, writing out the ThreadPoolWorkerThreadStart event causes a crash.
                Steps:
                1. Build the tip of https://github.com/dotnet/installer. The latest official build does not consume the latest runtime yet.
                2. Start a PerfView session: PerfView.exe collect /ThreadTime
                3. Run dotnet new console
                The following is output:
                Fatal error. Internal CLR error. (0x80131506)
at System.Diagnostics.Tracing.NativeRuntimeEventSource.ThreadPoolWorkerThreadStart(UInt32, UInt32, UInt16)
at System.Threading.PortableThreadPool+WorkerThread.WorkerThreadStart()
at System.Threading.Thread.StartCallback()

                This is the full stack under a debugger:
