Close https://github.com/llvm/llvm-project/issues/130080 Close https://github.com/llvm/llvm-project/issues/116087 The common pattern of the problem is the lambda is somehow leaked from a non-inline non-internal function in module purview, and we need to define a mangling for it by the discuss from https://github.com/itanium-cxx-abi/cxx-abi/issues/186 The root cause of the issue is a mismatch that give up too quickly when ManglingContextDecl is nullptr. But we can still get the context information from DC.
