> The resolved writer and resolved reader copy the writer's enum index into the
> reader's value without matching symbols by name
> (lang/c/src/resolved-writer.c:1739, lang/c/src/resolved-reader.c:1629). This
> causes the following issues:
> - A writer with enum [RED, GREEN] and reader with enum [GREEN, RED]: the
> resolved reader would assign the same index to a different symbol.
> - If the writer uses a symbol the reader doesn't have, the reader gets an
> out-of-range enum value instead of an error.
> The proposed fix maps writer symbols to reader symbols by name when the
> resolver is created, failing if a reader does not have a certain symbol.
