I can see how that could happen, but I'm not sure if it's desirable. IIRC, creating these functions produces some undesirable artifacts, and we actually do a fair amount of work to validate that we don't create lldb_private::Function objects for dead-stripped code. I think it would be illuminating to see how this function manages to get past the checks in SymbolFileDWARF::ParseFunction.
