 An internal data structure, the `UsedChunkList`, might be left in a corrupt state when an application terminates abnormally when writing to this data structure.
 In order to detect torn-writes on 32-bit, the data structure needs to be refactored.

+### Limitations
 
 In addition to the limitations of the 32-bit iceoryx, the mix-mode needs to ensure that all the data structures in shared memory have the same layout.
 While the `-malign-double` flag can be used for the iceoryx data types, it does not work for POSIX data structures like `sem_t`.
