Stack overflow during project build

[mokshinpv]

Version Used: dotnet\sdk\6.0.401

Steps to Reproduce:

1. Rebuild attached project in VS Community 2022 17.3.5:
   academitslearn2.zip
2. Getting stack overflow error

Expected Behavior: Code compiles.

Actual Behavior: Code doesn't compile.

Workaround: All worked in some old version of VS Community 2022.
Probably was old version of .NET SDK.

This project uses ANTLR which generates large classes.
I think somewhere Roslyn uses recursion which can't handle such large classes.

@mokshinpv can you please supply the stack you're getting when the overflow happens?

[mokshinpv]

@CyrusNajmabadi, VS doesn't show it, here is stack from Rider (attached in file).
stack.txt
Stack is large so can't copy it as text here.

Thanks. Fixed with #64322.

Same issue: SO, also only on the project with generated Antlr4 code in build.

Seems to happen only with some grammars. On a previously release with maybe 100 lines less of G4 definitions, but still a considerably large grammar, the MSBuild.exe does not trigger SO.

Tested msbuild also with preview of build tools 17.4.0 Preview 3, still StackOverflow. Co-worker will append repro to related open issue.
