This hopefully deciphers the error message Uncontrolled Memory Allocation https://stackoverflow.com/questions/64169882/how-to-solve-checkmarxs-issue-uncontrolled-memory-allocation Though Corion and haukex seem to have diagnosed it correctly. In plain words, you allow an external source (the size of the file and the size of each line of the file) to dictate to your program how much memory to allocate for reading it in, risking memory exhaustion. You need to keep Checkmarx happy and your supervisor happy. CheckKarlMarx would have said "a spectre is haunting you".
