Hi, reported two places might invoke twice of fclose, aof.c#L1211 and rdb.c#L1008, they are similar as followed:
if (fclose(fp) == EOF) goto werr;
........
werr:
.......
fclose(fp);
........
while invoking twice of fclose is undefined behavior, you might want to take a look. (reference to the RETURN VALUE part of https://linux.die.net/man/3/fclose)
