Stack overflow in crossgen2

[filipnavara]

Tried this 3 times on a clean checkout (commit 08b3170) on macOS 12.3.1 (M1 ARM host):

• Install prerequisites through brew
• Run ./build.sh
• Get this:

...
  ILCompiler.ReadyToRun -> /Users/filipnavara/Projects/runtime/artifacts/bin/ILCompiler.ReadyToRun/arm64/Debug/ILCompiler.ReadyToRun.dll
  crossgen2 -> /Users/filipnavara/Projects/runtime/artifacts/bin/coreclr/OSX.arm64.Debug/crossgen2/osx-arm64/crossgen2.dll
  crossgen2 -> /Users/filipnavara/Projects/runtime/artifacts/bin/coreclr/OSX.arm64.Debug/crossgen2/osx-arm64/publish/
  Stack overflow.
  Repeat 669 times:

Reproduces on mine (m1 mac mini, macOS 12.3) as well:

Stack overflow.

[filipnavara]

Yep, I got both of these messages on different runs (Consistency check failed first, followed by clean, and then I got the one in the original post).

[EgorBo]

From what I see it happens only on "published" crossgen (even when it's invoked without arguments) - doesn't reproduce if I run it from sources via dotnet run

[EgorBo]

I assume crossgen does not use NativeAOT on macos-arm64?

[trylek]

I believe that's what @agocke told me the last time, on OSX we don't use NativeAOT.

[mangod9]

assume this repros only on macOS 12.3 and not earlier versions?

[filipnavara]

I assume it reproduces on older versions too. In fact, 12.3 is not even the newest, I was just lazy to update.

[agocke]

Correct, this is R2R single-file.

I am seeing a somewhat similar problem on windows when using a recent SDK from dotnet/installer (7.0.100-preview.6.22313.7) and replacing the bits with checked clrjit.dll, coreclr.dll and SPC.dll from a recent build. On dotnet.exe new console I then hit the same stack overflow and assertion that @EgorBo wrote above.

In debugger the stack trace looks like:

It does not reproduce with #66887 reverted, though I hit other issues then so maybe the SDK just does not get to the problematic part. But cc @trylek anyway.

EDIT: After a fresh merge from main I no longer hit this problem, so maybe it is already resolved. The commit I was hitting the problem on was 2c110b6.
