in thread 5.10 shows uninitialized $@ warning

Bad example. 1/0 produces a compile-time exception in 5.8. Once you fix that, both behave identically and contrary to the OP's results. 
use warnings;

my $denum = 0;
eval { local $SIG{'__DIE__'} = sub { die $@ };
     print 1 / $denum;
};

print "[$@]\n";

    It was a perfectly fine example (in terms of the op's original conditions ;-)

      Your code never gets to execute the eval, much less to using $@ afterwards, so you couldn't possibly get the a warning from using $@. That's like saying "I can't replicate the fact that you got 'foo' on the screen, but ignore the fact that I didn't actually call a print function."

        Bullshit - under 5.10 at least - and whether or not it gets executed under perl 5.8 is irrelevant in terms of the original post. (It's the 5.10 behaviour that the op is interested in.)

        Let's just agree to have our respective lawyers sort this out tomorrow.
