[jira] [Created] (ARROW-9285) [C++] Detect unauthorized memory allocations in function kernels

Wes McKinney created ARROW-9285:
-----------------------------------

             Summary: [C++] Detect unauthorized memory allocations in function kernels
                 Key: ARROW-9285
                 URL: https://issues.apache.org/jira/browse/ARROW-9285
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney


If a function has been configured to preallocate space, then executing the kernel should not replace the preallocated buffer during execution -- this is an implementation error. Detecting this would be relatively easy and improve debugging for kernel implementers
