----------------------------------------

             Summary: [C++] Typo that causes segfault with unknown functions in Substrait
                 Key: ARROW-16152
                 URL: https://issues.apache.org/jira/browse/ARROW-16152
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Dewey Dunnington


There is a typo in {{ExtensionSet::Make()}} that causes a crash whenever somebody provides an unsupported function into the Substrait consumer. It looks like this was a copy/paste error here where {{type_ids}} should be {{function_ids}}.

https://github.com/apache/arrow/blob/a935c81b595d24179e115d64cda944efa93aa0e0/cpp/src/arrow/engine/substrait/extension_set.cc#L167-L168
