Thanks for the report!  I have no idea whether this can be considered
a Perl bug, a problem in your architecture, or whatever.  I leave this
to the author of Cwd, if only I could find one in the sources.  I'll
use `perlbug' to submit it :(


In any case, this is a bad news for autoreconf, which I suppose, can
no longer use Cwd:chdir.


I'm installing the following patch:

Index: ChangeLog
from  Akim Demaille  <address@hidden>

        * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
        (chdir_init) might hang when stat'ing mounted directories.
        Reported by Vance Shipley.
