Memory Leak

[moodeerf]

Hi sir,
When I used the "valgrind tool" to check the memory leak on linux, a memory leak is present in the "latgen-faster" executable program.

128 bytes in 1 blocks are still reachable in loss record 61 of 67

Thanks, does this cause any trouble? Do you know how to fix it?
