Version Used:

.NET SDK:
Version: 8.0.300
Commit: 326f6e68b2
Workload version: 8.0.300-manifests.4e5ea2d8
MSBuild version: 17.10.4+10fbfbf2e

Runtime Environment:
OS Name: Windows
OS Version: 10.0.19045
OS Platform: Windows
RID: win-x64
Base Path: C:\Program Files\dotnet\sdk\8.0.300\

Steps to Reproduce:

  1. Use dotnet new console to create a fresh project.
  2. Replace contents of Program.cs with just var elems = (path is not null ? [new Tuple<string>(path)] : Enumerable.Empty<Tuple<string>>());
  3. Run dotnet build and observe enormous internal compiler callstack.

Interestingly, if I remove the new Tuple<string> aspect, I get the desired effect: var elems = (path is not null ? [path] : Enumerable.Empty<string>()); does not crash, but yields the desired CS0103 diagnostic. It also does not have to be Tuple that is used; I originally identified the problem using a record type specific to a separate project. The null check does appear to be required. Naturally, defining path to be a string? with some value causes the program to compile successfully.

Diagnostic Id:

None, since the compiler crashes, but CS0103 would be expected.

Expected Behavior:

The expectation is that since path is not defined anywhere that we would receive error CS0103: The name 'path' does not exist in the current context.

Actual Behavior:

113 errors from a giant callstack:
