Expected behavior
The program does not try to free invalid memory
Environment
swift-driver version: 1.127.11.2 Apple Swift version 6.2 (swiftlang-6.2.0.16.14 clang-1700.3.16.4)
Target: arm64-apple-macosx26.0
Additional information
On Swift 6.1.2, the same code causes the compiler to abort at compile time, which seems better but the error message is scary:
error: compile command failed due to signal 6 (use -v to see invocation)
