according to the getline(3) documentation, the calling code needs to free the buffer even if getline fails. dmenu currently doesn't do that which results in a small leak in case of failure (e.g when piped /dev/null) $ ./dmenu < /dev/null ==8201==ERROR: LeakSanitizer: detected memory leaks Direct leak of 120 byte(s) in 1 object(s) allocated from: #0 0x7f6bf5785ef7 in malloc #1 0x7f6bf538ec84 in __getdelim #2 0x405d0c in readstdin dmenu.c:557 moving `line = NULL` inside the loop body wasn't strictly necessary, but IMO it makes it more apparent that `line` is getting cleared to NULL after each successful iteration.
