Stack overflow in `ErrorFacts.IsBuildOnlyDiagnostic`

[RikkiGibson]

I believe this is a recurrence of #80569. This repros both with the built-in language server in the C# extension and with a locally-built language server (see steps below).

The crash seems to occur when computing semantic classifications for ErrorFacts.IsBuildOnlyDiagnostic. Generally opening this file in the context of a code review (using vscode-pull-request-github) has been how I encounter the issue.

Local build steps

I used a locally built Release mode version of the language server from commit 4c279b2.

I used the following command to build the language server:
dotnet build src\LanguageServer\Microsoft.CodeAnalysis.LanguageServer\ -r win-x64 -c Release

Then I used the following VS Code setting to use the resulting language server (note that an absolute path is required):
"dotnet.server.path": "F:\\src\\roslyn\\artifacts\\bin\\Microsoft.CodeAnalysis.LanguageServer\\Release\\net9.0\\win-x64\\Microsoft.CodeAnalysis.LanguageServer.dll"

Note

I don't repro the problem when building in debug mode. It appears that with the debug language server, semantic classification of IsBuildOnlyDiagnostic is proceeding successfully, just slowly. I am unsure what is causing the behavioral difference.

Also note that I am using both the C# v2.94.71 and C# Dev Kit v1.70.3 extensions, in VS Code v1.105.1.

Since we are unable to repro in Debug builds, it's a bit difficult to diagnose what is going on (I investigated the previous issue and the captured info from the crash didn't provide enough info like what is in all locals). Perhaps we could add some logging or something similar locally to diagnose the crash (since we can repro by building roslyn locally).

[AlekseyTs]

@jjonescz, @RikkiGibson I recommend finding a way to capture a minidump with heap information. If you are able to debug live locally, we can try doing this together. Also, often debugger doesn't cooperate much once a stack overflow happens. Therefore, it might be worth trying to force a different kind of exception before this happens. For example, locally we can add a [ThreadStatic] and increment it on entry into the function that is a suspect for a deep recursion, and decrement it on exit. Once the value reaches a big enough number (like 50), throw an exception. Attempt to debug when the exception is thrown.

[jjonescz]

Although the following doesn't crash with stack overflow for me, it seems to go into the recursion through Filter same as the crashing scenario.

Note that the ErrorCode enum is not defined in the compilation, hence the switch erroneously binds the patterns as type tests (e.g., code is ErrorCode.WRN_ALinkWarn i.e., code is <error type>). I can observe that same behavior in the real crash though (not sure why IDE has the semantic model with just a single file, perhaps it's some intermediate state, or related to file-based app handing).

Brace yourself for long code ahead

@jjonescz Thanks, this made the nature of the issue more clear. In VS Code, when the file is opened before the project is fully loaded, we proceed by treating it as a rich misc file. So it is put into a compilation by itself with a standard set of references and the latest TFM for the SDK found by the tooling. I think that's how this situation is arising.
