I suspect the problem is that: 

sub save {
    @saved = ($@, $!, $^E, $,, $/, $\, $^W);
    $, = ""; $/ = "\n"; $\ = ""; $^W = 0;
}

[download]
from perl5db.pl doesn't mention $. (though the real solution may be about the opposite of that -- I haven't given it enough thought).

Dive right in and patch that and see if it makes a difference. If so, I'm sure you could send your patch in as a bug using perlbug and we'd all benefit.

While your at it, patch in a option so that $^W = 0 can be $^W = 1 so you can use the debugger to interactively play with warnings. (:
