fatal error release build of C++ library component #7397

Closed dabrahams closed 9 months ago

dabrahams commented 9 months ago

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

Description

Check out the spm-bug-release-build-fatal-error tag of https://github.com/hylo-lang-hylo and swift build -c release. It crashes with no useful diagnostic every time it gets to building shim.cc. If the build is invoked with swift test -c release iit will reporterror: fatalError` but that's it.
