Comment 10 for bug 1814532

With the bionic packages:

 *** 2:4.7.6+dfsg~ubuntu-0ubuntu2.6 500
        500 http://br.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages

Running:
smbclient //localhost/pub -U ubuntu%ubuntu -c "pwd;dir;cd dir1;dir;pwd;cd dir11; pwd; dir; cd /; cd dir2; pwd; dir; cd /"

Server valgrind report:
==3887== LEAK SUMMARY:

After update:

==7133== definitely lost: 24 bytes in 1 blocks

I was hoping the original reported would have tried the updated packages, since he seemed quite affected by this memleak. But in the meantime, this is the verification I can do.
