Description

Builds of the Swift AWS Lambda Runtime crashes on Linux when portion of code uses Synchronization's Mutex class.

As a workaround, we use NIOLockedValueBox instead and that works on 6.0.3 Linux

Reproduction

git clone https://github.com/sebsto/swift-aws-lambda-runtime.git
cd swift-aws-lambda-runtime
git fetch --all
git checkout sebsto/compiler_crash_mutex

docker run -it --rm -v .:/work swift:6.0-noble bash -c "(cd /work && swift build)"
