Subject: Debug.rb and exceptions


Hi,

I'm trying to debug a program that uses ftools.rb to rename (mv)
a file, and I get the following:

/usr/lib/ruby/1.6/ftools.rb:71: `Invalid cross-device link - 
"/tmp/functies.20443.rb"' (Errno::EXDEV)
        from /usr/lib/ruby/1.6/ftools.rb:71:in `move'
        from trans3.rb:577:in `main'
        from trans3.rb:589
/usr/lib/ruby/1.6/ftools.rb:71:      rename from, to

I look at ftools.rb, and see that it does something like:
 
    begin
      rename from, to
    rescue
      begin
        symlink File.readlink(from), to and unlink from

Because I want to mv a file between filesystems, the rename raises an
exception, which  the debugger catches.
Question: how can I avoid this. I haven't seen anything in the debug.rb
documentation (?) on this issue. It should be fairly common, I would
suspect.

Cheers,
