geoff,

i have been having trouble with duping in 2.0.94 (powerpc-linux). the best
test i can think of is agetty (in util-linux, add -fsigned-char
-DDEBUGGING). it dies shortly after trying to dup. also (i think) this is
why dpkg-deb fails on newer kernels, after trying to use a bad file
pointer. have you (or anybody) had any trouble like this?

matt.
