Diagnostic ID: AD0001

Analyzer source

SDK: Built-in CA analyzers in .NET 5 SDK or later

Version: 9.0.100-preview.7.24380.2

Describe the bug

When building the .NET 9 Preview 7 tag using the VMR on RHEL 9 on arm64, I got this error:

CSC : error AD0001: Analyzer 'Microsoft.Interop.Analyzers.CustomMarshallerAttributeAnalyzer' threw an exception of type 'Syst       em.InvalidProgramException' with message 'Common Language Runtime detected an invalid program.'. [/builddir/build/BUILD/dotnet-v9.0.0-preview.7.24405.7-x64-bootstrap/src/sdk/src/BlazorWasmSdk/Tasks/Microsoft.NET.Sdk.BlazorWebAssembly.Tasks.csproj::TargetFramework=net9.0]

This seems to be a random error. It doesn't happen on all arm64 platforms, or on all builds.

Steps To Reproduce

Provide the steps to reproduce the behavior:

1. git clone https://github.com/dotnet/dotnet
2. git checkout v9.0.0-preview.7.24405.7
3. ./prep-source-build.sh
4. ./build.sh --source-only /p:OfficialBuilder=CentOS /p:MinimalConsoleLogOutput=false /p:ContinueOnPrebuiltBaselineError=true /v:n /p:LogVerbosity=n
5. Get this error, randomly

Expected behavior

The VMR builds, just like it does most of the time

Actual behavior

This error makes the VMR build fail

Moving to runtime as CustomMarshallerAttributeAnalyzer lives there

There's no reason for the analyzer to be throwing an InvalidProgramException as it's just regular C#.

I wouldn't be surprised if the underlying issue for dotnet/dnceng#3305 was related.

Agreed, marking this as dup of dotnet/dnceng#3305
