System: NetBSD araneus.pp.fi 1.0A NetBSD 1.0A (GUANO) #4: Mon Jul 3 17:08:45 EET DST 1995 gson@araneus.pp.fi:/usr/src/sys/arch/i386/compile/GUANO i386


>Description:
	When /usr/bin/tr is given arguments containing characters 
	with the eighth bit set, it behaves erratically.  This is due
	to sign extending such characters into negative numbers and
	then using those negative numbers as array indices.

>How-To-Repeat:

	Uudecode the following shell script and then run it with itself
	as standard input like this: "sh trbug <trbug".  The output should
	not be identical to the input, but it is.

	   begin 644 trbug
	   7(R$O8FEN+W-H"G1R("?D]B<@)V%O)PKW
	   `
	   end

>Fix:

Apply this patch to /usr/src/usr.bin/tr/extern.h.
