Someone else reported this to me a couple of weeks ago, and I remain
baffled. Try writing a simple program that opens (and closes)
/dev/profile -- see if that works. Try deleting the /dev/profile node
and then recreating it. See if "ls -l /dev/profile" works (vs.
something like "ls -l /dev/profile*") to see if there might be some
unprintable character in the namespace. And please let me know what you
discover.
