+
+g++-14 does more checks even on _unexpanded_ templates; hence this
+new error that did not show up in g++-12.
+
+Building encode.cc under g++-14 yielded:
+
+```
+./../include/fst/fst.h:690:59: error: no match for 'operator=' (operand types are 'std::unique_ptr<fst::SymbolTable, std::default_delete<fst::SymbolTable> >' and 'fst::SymbolTable*')
+ 690 |     isymbols_ = impl.isymbols_ ? impl.isymbols_->Copy() : nullptr;
+```
