```
10,463 (48 direct, 10,415 indirect) bytes in 1 blocks are definitely lost in loss record 34,138 of 34,479
at 0x484386F: malloc (vg_replace_malloc.c:393)

and
```
2,051 (144 direct, 1,907 indirect) bytes in 3 blocks are definitely lost in loss record 33,018 of 34,479

Testing Done:
Ran in `valgrind --leak-check=full` and confirmed that the leak was gone.
