Sure, thanks for your help!
> "std::bad_cast" on mac os when reading from FlightStreamReader
> --------------------------------------------------------------
>
> Key: ARROW-15669
> URL: https://issues.apache.org/jira/browse/ARROW-15669
> Project: Apache Arrow
> Issue Type: Bug
> Components: FlightRPC
> Affects Versions: 6.0.0, 7.0.0
> Reporter: Yifei Yang
> Priority: Major
> Attachments: 0001-mac-flight-crash-test.patch,
> FlightMacExceptionTest.cpp, Main.cpp, fix_build_on_mac.cmake,
> stacktrace-mac-exception.txt

> When calling "FlightStreamReader::ReadAll()", got "std::bad_cast exception"
> (this is on 6.0.0, on 7.0.0 got "segmentation violation signal"). This
> happens only on mac os, it works fine on linux (tested on ubuntu).
> Code snippet:
> Construction of FlightDataStream inside server's DoGet():
> {{auto schema = ::arrow::schema({}}
> {{
> {field("f0", ::arrow::int32())}
> ,}}
> {{
> {field("f1", ::arrow::int32())}
> ,}}
> {{
> {field("f2", ::arrow::int32())}
> ,}}
> {{});}}
> {{auto array_0_0 = Arrays::make<::arrow::Int32Type>(\{0, 1, 2, 3, 4, 5, 6, 7,
> 8, 9}).value();}}
> {{auto array_0_1 = Arrays::make<::arrow::Int32Type>(\{10, 11, 12, 13, 14, 15,
> 16, 17, 18, 19}).value();}}
> {{auto array_0_2 = Arrays::make<::arrow::Int32Type>(\{20, 21, 22, 23, 24, 25,
> 26, 27, 28, 29}).value();}}
> {{auto rb_0 = ::arrow::RecordBatch::Make(schema, 10, \{array_0_0, array_0_1,
> array_0_2});}}
> {{auto rb_1 = ::arrow::RecordBatch::Make(schema, 10, \{array_0_0, array_0_1,
> array_0_2});}}
> {{auto rb_reader = ::arrow::RecordBatchReader::Make(\{rb_0, rb_1});}}
> {{return std::make_unique<::arrow::flight::RecordBatchStream>(*rb_reader);}}
>
> Retrieve record batches from stream at client:
> {{std::unique_ptr<::arrow::flight::FlightStreamReader> reader;}}
> {{st = client->DoGet(ticket, &reader); // ticked is well constructed}}
> {{{}std::shared_ptr<::arrow::Table> table;{}}}{{{}st =
> reader->ReadAll(&table);{}}}
>
> Thanks!
