[GitHub] [celix] pnoltes commented on issue #289: Possible NULL pointer dereference in the method manifestParser_parseExportHeader??

   Theoretically `clauses` can be null if the underlining call to `linkedList_create` fails. 
   
   This would mean the malloc in the linkedList_create should fail at:
   https://github.com/apache/celix/blob/0729c4dfaa6b45f436e41f13ebe71960c746d109/libs/utils/src/linked_list.c#L35
   
   Celix has the approach not to check malloc, because in practices malloc calls will always return a value (pointer to mem or virtual pointer) and if memory becomes an issue the oom killer will kill the process.

   So in short, no this cannot happen.
