The bug is in your lack of shell quoting, and not in tr.  To see why this
is not a tr bug, you can do:

# echo hello | echo tr [:lower:] [:upper:]

> 
> address@hidden:# echo hello | tr [:lower:] [:upper:]

You meant to use:

# echo hello | tr '[:lower:]' '[:upper:]'

Otherwise, the shell sees the unquoted [:lower:] as a glob, and if any
files happen to match the glob (in this case, the files ':', 'l', 'o',
'w', 'e', or 'r'), then glob expansion names those files rather than a
bracket expression.
