jonkeane opened a new issue, #45718: URL: https://github.com/apache/arrow/issues/45718
### Describe the bug, including details regarding any error messages, version, and platform. Since #45562 (and the error also suggests this PR), we have seen the `test-r-rstudio-r-base-4.1-opensuse155` crossbow job fail with: ``` [ 59%] Building CXX object src/arrow/CMakeFiles/arrow_compute.dir/compute/kernels/aggregate_pivot.cc.o /arrow/cpp/src/arrow/compute/kernels/aggregate_pivot.cc: In function ‘arrow::Result<std::unique_ptr<arrow::compute::KernelState> > arrow::compute::internal::{anonymous}::PivotInit(arrow::compute::KernelContext*, const arrow::compute::KernelInitArgs&)’: /arrow/cpp/src/arrow/compute/kernels/aggregate_pivot.cc:152:10: error: could not convert ‘state’ from ‘std::unique_ptr<arrow::compute::internal::{anonymous}::PivotImpl, std::default_delete<arrow::compute::internal::{anonymous}::PivotImpl> >’ to ‘arrow::Result<std::unique_ptr<arrow::compute::KernelState> >’ return state; ^~~~~ make[2]: *** [src/arrow/CMakeFiles/arrow_compute.dir/build.make:496: src/arrow/CMakeFiles/arrow_compute.dir/compute/kernels/aggregate_pivot.cc.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:2045: src/arrow/CMakeFiles/arrow_compute.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs.... ``` I suspect this is the old(er) GCC compiler in opensuse155 (7.5) which is EOL so we should probably bump the 4.1 test to a different OS. ### Component(s) Continuous Integration, R -- This is an automated message from the Apache Git Service.
