 Hi All,

 When I try to touch a file in a filesystem mounted using sshfs, the
 machine crashes hard, requiring four-second-button-press.

 I cleaned and reinstalled sshfs and its dependencies. The install process
 went like this:

 {{{

 As you can see, all the dependencies were installed fresh.

 However, the hard crash results. I will attach a sample session (in which
 I simply mount the remote fs with -d in case that's of any use), and the
 kernel crash log which is presented to me after the reboot! If instead of
 attempting to use it, I unmount the filesystem using umount, the sshfs
 process terminates and all is well!

Comment:

 Sounds like a bug that should be reported to the developers of sshfs.
