Missing symbols for Windows ARM64 native binaries on https://msdl.microsoft.com/download/symbols with the 8.0.12 patch.

[PDeets]

Description

On https://msdl.microsoft.com/download/symbols, symbols are available for x86 and x64 Windows, but are missing for ARM64 Windows with the following binaries:

• clrgc.dll
• clrjit.dll
• coreclr.dll
• createdump.exe
• mscordaccore.dll
• mscordaccore_arm64_arm64_8.0.1224.60305.dll
• mscordbi.dll

They are present for 8.0.11, but missing for 8.0.12.

Reproduction Steps

Download the Windows ARM64 runtime artifacts for 8.0.12 (and 8.0.11 for comparison):

• 8.0.12: https://download.visualstudio.microsoft.com/download/pr/ad6302ea-b7a6-4b83-8dcc-c932f9b8d037/5379348874d0ab07165734552a050b88/dotnet-runtime-8.0.12-win-arm64.zip
• 8.0.11: https://download.visualstudio.microsoft.com/download/pr/3b250d28-7fae-473c-a064-c312c35ca7c8/bc1771d6d4b7dd9dbe6fbb417b9ef1e6/dotnet-runtime-8.0.11-win-arm64.zip

Extract coreclr.dll from the shared\Microsoft.NetCore.App\8.0.12 (or 8.0.11) folder.

Get symchk.exe from the debugging tools for Windows. (https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/using-symchk)

Run this command while in the folder that contains coreclr.dll:
symchk.exe /s SRV*https://msdl.microsoft.com/download/symbols /if coreclr.dll /oc . /v

The output will show the PDB is missing from the symbol server for 8.0.12:

Expected behavior

Symbols for Windows ARM64 native binaries in 8.0.12 should be published to https://msdl.microsoft.com/download/symbols.

Actual behavior

Symbols for Windows ARM64 native binaries in 8.0.12 are missing on https://msdl.microsoft.com/download/symbols, although they are present for x86 and x64, and for the ARM64 build of 8.0.11.

Regression?

Yes, the symbols are available for 8.0.11.

Known Workarounds

If you are a Microsoft employee, you can point to the Microsoft-internal symbol server instead. The Windows ARM64 binaries for 8.0.12 are present on the Microsoft-internal symbol server.

FYI. This issue persists with the .NET 8.0.13 release that came out today.

[PDeets]

FYI. This issue is present in the .NET 8.0.14 release that came out today as well.

[PDeets]

FYI. This still exists in today's .NET 8.0.15 release.

[PDeets]

Actually, it looks like my pipeline's usage of the following task still installed 8.0.14:

    - task: UseDotNet@2
      displayName: 'Install .NET 8'
      inputs:
        version: '8.0.x'

Because of this, I have not yet assessed whether the issue still reproduces for 8.0.15. I'll have to wait until the UseDotNet command picks up the new version that was released today before my pipeline can tell me if the known issue is still there.

[PDeets]

I ran the pipeline again today and confirmed the ARM64 symbols are still missing for 8.0.15.

[hoyosjs]

Updating again - this was missing from MSDL only for ARM and ARM64. we have a root cause and it's been routed to the appropriate team.

[oleksandr-didyk]

The release team has re-published the missing PDBs and have verified them for previous releases for the impacted dll (from 8.0.11 to 8.0.16) on the public sym server. The issue with publishing during .NET release has been found and will be resolved for 8.0.18.

If there are any other similar issues with missing symbols please do let us know. I apologize for the PDBs not being available for so long 🙇

[PDeets]

I confirmed the ARM64 symbols are present on the external symbol server for the 8.0.17 release that went out last week. I'm closing the issue now.
