Crash with 2024-08-26/6.1 toolchain/C++ interop #76104

Closed mattwhiteside closed 2 months ago

mattwhiteside commented 3 months ago

Description

Trying to create a swift library that links in a C++ library.

Reproduction

I'm trying to compiling the following the C++ code, but extracted into a library:

https://github.com/smarr/SOMpp

The C++ library/code compiles ok on its own. Trying to compile a swift library that links it crashes, even when everything in the umbrella header is commented out.

I've specified the build settings for the C++ library via a Package.swift file (seemed much easier than doing it with Cmake).

Expected behavior

Compiler doesn't crash.

Environment

swift-DEVELOPMENT-SNAPSHOT-2024-08-26

I'm running this build via Xcode Version 16.0 beta 6 (16A5230g).

Additional information

No response

I'm experiencing the same crash / stack trace when trying to build the swift-cmake-examples/4_swift_macros at main · apple/swift-cmake-examples project.

Environment

swift-DEVELOPMENT-SNAPSHOT-2024-09-06 Building from command line on macOS Sonoma 14.6.1

Additional information

Build works OK when using the toolchain bundled with Xcode 15.4

ebariaux commented 2 months ago

FYI the crash I was experiencing is fixed with the swift-DEVELOPMENT-SNAPSHOT-2024-09-11-a version.

Thank you. Yes it's working now for me too.
