Last cvsup/world/kernel is from around midnight last night, but noticed
the problem yesterday. For a csi class I have to sort and uniq a file
in c, and as a test case, I wrote a simple hex dump that respects
newlines. No matter what I give it as input, it will hard crash the
system. No DDB, no panic, just hard locked. When trying to run it
under GDB, break on main, as soon as I type run, it dies again. Im
writing it on the same machine with much more significant programs
running absolutely perfectly. I'm attaching the source to see if it's a
common problem with anyone else.
