나는 레지스터 할당이 유효화 분석 구현이 있고, 나는 독방 감금 오류가 점점 오전 : 오류가이 명령 iwth 무엇인지 보려고,읽기 malloc에 출력
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7560d9d in _int_malloc() from /lib64/libc.so.6
그래서 나는 Valgrind의 그것을 실행 :
valgrind -v --leak-check=yes
나는 전에이 프로그램을 사용한 적이 없으며 seg 오류가 발생하는 이유를 알지 못합니다. 나는 어딘가에서 메모리 누출을 의심하고있다. valgrind의 결과가 무엇인지 이해하는 데 도움을 줄 수 있습니까?
