[Bug-readline] Readline memory leak

[Anil Motilal Mahtani Mirchandani]

Hello,

I am using libreadline 6.1 and I've found that valgrind reports still reachable memory. It's a very simple piece of code:

> #include <stdlib.h>
> #include <readline/readline.h>
>     
>
> int main()
> {
>     char *buf;
>         
>         while((buf = readline("Hello: "))!=NULL) {
>                 if(strcmp(buf,"exit") == 0){
>
>                     free(buf);
>                     break;
>                 }
>                 free(buf);
>     }
>
>
>     return 0;
> }


And here is the valgrind output:

I just wanted to know if this is supposed to be this way or if it's some kind of bug.

Thanks in advance.
