             Summary: [C++] UBSAN error "applying non-zero offset to null 
pointer"
                 Key: ARROW-13440
                 URL: https://issues.apache.org/jira/browse/ARROW-13440
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Weston Pace


Clang's ubsan considers a non-zero offset being added to a null pointer to be 
undefined behavior.  This causes ubsan violations in our test suites if you are 
using clang-10 or higher.

This was not detected by CI since CI uses clang-8 and this check was added in 
clang-10 [1][2].
