>Description:
  After upgrading mc port from 4.5.54_2 to 4.6.0_2 using of cvsup and
  portupgrade procedure I have in result broken mc. When I run mc it hangs.
  The only way to kill it is to execute "killall mc" from another console.
  Since CPU utilization is pretty high when mc is "hung", I think something
  is looping. If I roll back to mc-4.5.54_2, it works fine, so it is not
  kernel-related.
  I ran mc under truss trying to figure out what it is doing.
  Here is the tail of log truss mc on alpha:

>How-To-Repeat:
  cvsup ports as of 04/01/03 and install /usr/ports/misc/mc port on alpha system.
  Run mc and it will hang.

>Fix:
  When I roll back to mc-4.5.54_2, it works fine.
