    Thanks for your reply, but does perl put all list assignments together? otherwise you can't explain why it still throw out of memory when example 2running

      That's because you used literals, so the range operator is expanded at compile time. If you used 
      my $max = 2e7;
my @aa = 1 .. $max;
my @bb = 1 .. $max;

      You'd get no error, as the lists are expanded at runtime and immediately thrown away.

        Thanks!! your replies perfectly answer my question. I can't still believe perl list assignment has the flaw/bug like this though. I will use list assignment at runtime at most.
