@amoeba : I could finally install arrow with my patch (on Linux/Ubuntu). I re-ran my my patch with using the `gdb` debugger and got the same error as you. The debugger output is the following: ``` arrow::acero::RowArrayMerge::CopyVaryingLength (target=<optimized out>, source=..., first_target_row_id=<optimized out>, first_target_row_offset=<optimized out>, source_rows_permutation=0x7ffcc8052020) at /home/onyxia/work/arrow/cpp/src/arrow/acero/swiss_join.cc:605 605 *target_row_ptr++ = *source_row_ptr++; ``` [Line 605 of swiss_join.cc](https://github.com/oliviermeslin/arrow/blob/fb2617833200d9c90b6d79a85ae9e840b41938da/cpp/src/arrow/acero/swiss_join.cc#L604) is part of the following loop, where the content of source rows is iteratively added to target rows: ``` for (uint32_t word = 0; word < length / sizeof(uint64_t); ++word) { *target_row_ptr++ = *source_row_ptr++; } ``` As I am completly new to C++, I'm not sure what this bug means. My intuition is that we're trying to add too much to the `target_row_ptr` pointer given its type. Would you or @westonpace have any clue on what is going wrong? -- This is an automated message from the Apache Git Service.
