C로 색인작업중인데 메모리가 문제 인거 같은데;;

gdb 결과가 이렇습니다.

검색을 하고 찾아보던중에
export MALLOC_CHECK_=0 이옵션을 하면
임시방편이지만 해결하수있다해서 /etc/profile에 추가도 해보고
이것 적것해봤는데 안되네요

그래서 valgrind를 해봤는데

에러가 없는건지
malloc free할떄 마다 찍어주는데서는
--24265-- free(0x40183C0)
--24265-- free(0x4018348)
[FAILURE: -1]
--24265-- free(0x0)
--24265-- free(0x0)
--24265-- free(0x0)
--24265-- free(0x0)
요렇게 나오는 부분도 있는데
어떻게 해결해야할까요?
