Comment 8 for bug 1814532

I'm not sure this is robust enough as a test case, that's why I'm adding it here instead of in the test caseh, but I ran smbd under valgrind before and after the update, and less bytes were lost for the same smbclient connection:

before:
==3977== LEAK SUMMARY:
==3977== definitely lost: 72 bytes in 7 blocks

After:
==5438== LEAK SUMMARY:
==5438== definitely lost: 24 bytes in 1 blocks

The client command was (with a suitable smb.conf and /pub directory):
smbclient //localhost/pub -U ubuntu%ubuntu -c "pwd;dir;cd dir1;dir;pwd;cd dir11; pwd; dir; cd /; cd dir2; pwd; dir; cd /"
