Hello, I have a question related to this "Use of freed value in iteration". Is it possible for the "freed" value to to be replaced by some other value in memory unintentionally, via some unrelated variables?

For example, the following code will produce the "Use of freed value in iteration" error:

my $hr1 = {};
my $hr2 = {};
my $hr3 = {"$hr1" => $hr1, "$hr2" => $hr2};
my @values = sort values %$hr3;
print "@values\n";
foreach my $v (sort values %$hr3) {
  print "$v\n";
  delete $hr3->{$values[1]};
  # some_function()
}

but say some_function does a bunch of other stuff. Is it possible for the value of the second item in the foreach loop to spring back into existence? For example, if some_function reuses the memory location that $hr3->{$values[1]} once used?
