I don't think this is an Expect-related problem, I'd rather guess this
is a problem with the debugger in 5.8.0 given the fact that there are
plans to rewirte it from scratch...
Spawn does a fork() and this is where the debuggers problems probably
comes from, I'd guess that the debugger also has this problem with code
that does a simle fork(), without the Expect package loaded. (Actually
I'm astonished that debugging spawn() works at all in 5.6.0...)
