Thank you for this report!

Your observation is correct and another leak is opts.convertcp which
is allocated and never freed. However, this is only a minor leak because
this file is part of mount.vboxsf --- a process which has a very short
lifetime and all ressources are freed on process termination.

Kind regards,

Frank
