[6.0.1] Compiler crashes when attempting to compile Swift Foundation. Failed to reconstruct type. #76788

Open sbhat98 opened 1 week ago

sbhat98 commented 1 week ago

Description

When attempting to compile the latest branch of Swift Foundation (https://github.com/swiftlang/swift-foundation/) using the swift.org release of Swift 6.0.1 on MacOS, the compiler crashes.

Reproduction

  1. Clone https://github.com/swiftlang/swift-foundation/. (Tested when main pointed to b2d323e)
  2. Run swift test

Stack dump

Failed to reconstruct type for $s6Darwin14POSIXErrorCodeOD
Original type:
(enum_type decl="_errno.(file).POSIXErrorCode")
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.
Pass '-Xfrontend -disable-round-trip-debug-types' to disable this assertion.
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.

error: fatalError

Expected behavior

The code builds without error

Environment

$ swift --version

Apple Swift version 6.0.1 (swift-6.0.1-RELEASE)
Target: x86_64-apple-macosx15.0

Additional information

It's unclear if this is a regression from 6.0.0 since there was another issue causing this to be unable to be built in the previous version (https://github.com/swiftlang/swift/issues/76534)

ulian-onua commented 5 days ago

I can confirm that I also have a similar Swift Compiler crash when trying to build Swift Package for the iOS app.
