-* Memory is sometimes freed incorrectly freed when the simulations
-  end, causing a seg-fault; the impact of this bug is mitigated
-  because output has already been written at this time
-
 * A large amount of GPU memory for pairlists is allocated statically,
   which may cause out-of-memory crashes in older hardware
