Unused value
An assigned value that is never used may represent unnecessary computation, an incorrect algorithm, or possibly the need for cleanup or refactoring. A value assigned to a variable is never used.
/src/mongo/db/cst/cst_pipeline_translation.cpp:417: UNUSED_VALUE 116026 Overwriting previous write to "*&<temporary>" with value from "mongo::cst_pipeline_translation::<unnamed>::translateLiteralLeaf(mongo::CNode const &)::[lambda(std::vector<std::pair<mpark::variant<KeyFieldname, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, mongo::CNode>, std::allocator<std::pair<mpark::variant<KeyFieldname, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, mongo::CNode> > > const &) (instance 1)]()".
/src/mongo/db/cst/cst_pipeline_translation.cpp:416: UNUSED_VALUE 116026 Assigning value from "mongo::cst_pipeline_translation::<unnamed>::translateLiteralLeaf(mongo::CNode const &)::[lambda(std::vector<mongo::CNode, std::allocator<mongo::CNode> > const &) (instance 1)]()" to "*&<temporary>" here, but that stored value is overwritten before it can be used.
