I ran into this with 1.8.1 last week, where the end-of-file was not 
being detected when the input record separator is null. This seems to 
have been fixed in io.c (on 26 December 2003). It now works correctly in 
the CVS version:

~/src/ruby-1.8.0% ./ruby -v; ./ruby -0777 -ne 'puts $FILENAME' ran*
ruby 1.8.0 (2003-06-23) [i686-linux]
random.c
random.o
range.c
range.o

~/src/ruby-1.8.1% ./ruby -v; ./ruby -0777 -ne 'puts $FILENAME' ran*
ruby 1.8.1 (2003-12-25) [i686-linux]
random.c
random.c
random.c
random.c
random.c
random.c
...

~/src/ruby-cvs/ruby% ./ruby -v; ./ruby -0777 -ne 'puts $FILENAME' ran*
ruby 1.9.0 (2004-02-06) [i686-linux]
random.c
random.o
range.c
range.o
