mountd segfaults in NFSv4 if -alldirs is present in exports

[George Mamalakis]

Hi all,

the title explains it all...

But ok, let's be a bit more extensive.

If I have one line in /etc/exports reading:

V4:  /  -alldirs

and try to start mountd, it segfaults with signal 11. From the manpage I 
read that -alldirs is the "second method" used to export a filesystem 
and V4 is the "third", maybe implying that they are mutually exclusive. 
Nevertheless, I suppose that mountd shouldn't segfault in my case, it 
could just refuse to start giving an error message or something. I've 
tried a different /etc/exports containing a dummy option -dummy instead 
of -alldirs and mountd won't segfault, hence there's no problem with its 
parser.
