.NET 8.0.401 + macOS crashes, while .NET 8.0.303 doesn't.

[jonpryor]

Description

.NET 8.0.401 + macOS crashes, while .NET 8.0.303 doesn't.

Reproduction Steps

Alas, not minimal:

# Repro is from building the dotnet/java-interop repo
git clone https://github.com/dotnet/java-interop.git
cd java-interop
git checkout fcad3368815dffd0f38f64384aa21b0b65367d68
git submodule update --init --recursive


# ensure .NET 8.0.401 is used
export PATH=$HOME/Downloads/dotnet-sdk-8.0.401-osx-x64:$PATH

# prepare
dotnet build -t:Prepare Java.Interop.sln

# build
dotnet build Java.Interop.sln

Expected behavior

Build completes without error.

Note: requires that dotnet/java-interop dependencies already exist, which includes a C++ toolchain, Java SDK, etc.…

Actual behavior

Fails to build:

tmp7adcfcd1012f44439ffd2772eea8f2e1.exec.cmd: line 2: 89333 Segmentation fault: 11  "…/dotnet-sdk-8.0.401-osx-x64/dotnet" "…/java-interop/bin/Debug-net8.0//jnimarshalmethod-gen.dll" "…/java-interop/samples/Hello-NativeAOTFromJNI/bin/Debug/Hello-NativeAOTFromJNI.dll" -v -v --keeptemp -L "…/java-interop/samples/Hello-NativeAOTFromJNI/bin/Debug/"

[…/java-interop/samples/Hello-NativeAOTFromJNI/Hello-NativeAOTFromJNI.csproj]

Re-run with diagnostic logging enabled:

dotnet build -v:diag Java.Interop.sln > b.txt

and there isn't much additional output regarding the crash.

Regression?

Yes. This same repo builds with .NET 8.0.303. See also: dotnet/java-interop#1245

Known Workarounds

Use .NET 8.0.303.

Configuration

• .NET 8.0.401
• macOS Sonoma 16.4.1
• x64
• No idea if it's specific to this configuration
• Not using Blazor

Other information

This doesn't appear to fail on Linux-x64.

Note: you may need to run dotnet build Java.Inteorp.sln more than once to get to the crash. I've also seen this error, which doesn't repro:

I'm not (currently) reporting this MSB4018 from GenerateRuntimeConfigurationFiles.

@AaronRobinsonMSFT Did we make any servicing fixes that could have caused this?

[jkotas]

This might have been introduced by #104818 and fixed by #107199 .

If the crash occurs only under Rosetta and not on a real x64 macOS and there is some hardware exception handling going on, this could be what @jkotas said.

I was experiencing this on an x64 macOS machine. No arm64, no Rosetta.
