[GitHub] [arrow] bkietz commented on pull request #10882: ARROW-13567: [C++] ConvertOptions::Defaults leaves `timestamp_parsers` uninitialized

   A default constructed vector will be initialized to empty. A vector with bogus or uninitialized size means that the underlying memory was corrupted, we're accessing a dangling reference to ConvertOptions, or similar undefined behavior. If you have solid repro I would recommend running it through valgrind or ASAN
