      Description

      While running test_random_abort to answer the question about the child generating core files, I hit a double free error of an update structure crash.
      Here's the error:

      *** Error in `./test_random_abort': double free or corruption (out): 0x00007f5e20287ae0 ***
      

      Here's the stack:
