[C++][Fuzzing] Missing nullptr checks in IPC

    XMLWordPrintableJSON

Details

    Description

      arrow-ipc-fuzzing-test found the attached attached crashes. Reproduce with

      arrow-ipc-fuzzing-test crash-xxx
      

      The attached crashes have all distinct sources and are all related with missing nullptr checks. I have a fix basically ready.
