1. Apple Swift version 6.0-dev (LLVM ce41a43bba95b2b, Swift 1a840948a0905df)
2. Compiling with effective version 5.10
3. While evaluating request ExecuteSILPipelineRequest(Run pipelines { Mandatory Diagnostic Passes + Enabling Optimization Passes } on SIL for main)
4. While running pass #242 SILModuleTransform "Differentiation".
5. While processing // differentiability witness for f<A>(_:)

Expected behavior
The compilation should succeed, or the compiler should produce an error message indicating why the compilation cannot succeed.
