Ok, I have good news: it looks like a compiler error. The error pattern is very similar to https://developercommunity.visualstudio.com/t/Code-optimization-bug-SIMD-std::transf/10912292 and `std::copy` is used in precisely [one of the involved code paths](https://github.com/apache/arrow/blob/8b2336058c1dd5eba3293ab736cfbe8e0c38dc2b/cpp/src/parquet/column_writer.cc#L2015). https://developercommunity.visualstudio.com/t/Auto-vectorization-breaks-std::copy-in-V/10912564 It's supposed to be fixed in 17.14.8, I don't know when it's gonna be available on GH. https://learn.microsoft.com/en-us/visualstudio/releases/2022/release-notes?tabs=allfeatures#17.14.8 -- This is an automated message from the Apache Git Service.
