Description
While compiling swiftly on macOS with main-snapshot-2025-04-12 (6.2-dev) there's the following compiler crash:
Assertion failed: (p.isTrackingElement(op.getOpArg2()) && "Assign PartitionOp's source argument should be already tracked"), function apply, file PartitionUtils.h, line 1371.
Reproduction
- With a macOS 15.x Apple Silicon computer
- Install the main-snapshot-2025-04-12 Swift toolchain from swift.org (Apple Swift version 6.2-dev (LLVM 81ab6d9f7e4810f, Swift 9cc1947)
- Clone the main branch of swiftly here: https://github.com/swiftlang/swiftly
- Run
swift build --build-tests
Stack dump
error: compile command failed due to signal 6 (use -v to see invocation)
Assertion failed: (p.isTrackingElement(op.getOpArg2()) && "Assign PartitionOp's source argument should be already tracked"), function apply, file PartitionUtils.h, line 1371.
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.
