Weston Pace commented on ARROW-13567: ------------------------------------- I ended up getting to the bottom of this. My builds were relying on some old cmake files in CONDA_PREFIX/lib/cmake/arrow which referenced Arrow 5.0.0 libs so it was using 6.0.0 headers and linking to 5.0.0 libs. > [C++] ConvertOptions::Defaults leaves `timestamp_parsers` uninitialized > ----------------------------------------------------------------------- > > Key: ARROW-13567 > URL: https://issues.apache.org/jira/browse/ARROW-13567 > Project: Apache Arrow > Issue Type: Bug > Components: C++ > Reporter: Weston Pace > Assignee: Weston Pace > Priority: Major > Labels: pull-request-available > Time Spent: 1h 50m > Remaining Estimate: 0h > > This showed up when I was trying to build the cookbook which was calling > read_csv.
