It's not a bug. In coreutils, 'touch -' is documented to touch the standard output file, not a file named '-'. The POSIX specification for 'touch' allows either the coreutils behavior or the other behavior that you mentioned. If you want to touch a file named '-', the command 'touch ./-' is a portable way to do it.
