I've tested this on a recent build of Moose/Class::MOP. Here's my test
case:
test.pl:
---------------------------------------
use strict;
use warnings;
use Foo;
use Module::Refresh;
my $foo = Foo->new();
foreach (1..10) {
Module::Refresh->refresh;
$foo->do();
sleep 10;
}
Foo.pm:
---------------------------------------
package Foo;
use Moose;
with 'Bar';
sub do {
print "Do\n";
}
__PACKAGE__->meta->make_immutable;
1;
Bar.pm:
---------------------------------------
package Bar;
use Moose::Role;
1;
Now, start up test.pl and then modify the print() line in Foo.pm, notice the
errors. I get this:
Do
Subroutine do redefined at Foo.pm line 6.

Now, if I remove the `with 'Bar'` line OR the
`__PACKAGE__->meta->make_immutable` line the error goes away and everything
works as expected.
I'm a bit at a loss as to what the issue is. For now I'm just going to
remove the make_immutable lines during development.
