  • SR-15040 The 5.5 snapshot compiler for linux crashes with "SIL memory lifetime failure" when compiling the NIO tests

Issue Description:

When compiling the main branch of SwiftNIO with the latest Swift docker nightlies the compiler crashes (on compiling the tests).

Steps to reproduce:

  • Use latest Swift docker nightly:

    $> docker run --rm -t -v $(pwd):/src -w /src swiftlang/swift:nightly-main-focal swift --version
Swift version 5.6-dev (LLVM 7aef0efea99e2c6, Swift e4f71c8e118fc09)
Target: x86_64-unknown-linux-gnu

  • Compile SwiftNIO main branch:

    $> docker run --rm -t -v $(pwd):/src -w /src swiftlang/swift:nightly-main-focal swift build --build-tests
