Dominique, your test case had a bug, fixed as following:

- sub { test_waz_zere });
+ sub { &test_waz_zere });

or  sub { test_waz_zere(@_) });

also I did some updates for the recent changes in mp2 API, the whole test is at the end.

Now with threaded perl 5.8.6 everything works fine, but:
t/directive/perlrequire fails with: can't find ANONSUB top entry (get)

with non-threaded 5.6.1 a bunch of tests fail with:
Undefined subroutine &main::ÿÿÿÿÿÿÿÿÿÿÿÿÿ called, <DATA> line 462.

so I'll be looking at those cases.

Thanks for the test case!

package TestHooks::inlined_handlers_server_wide;

# this test exercises Apache handlers as anonymous subs, installed
# using Apache->server->push_handlers() at mod_perl initialization
# time.
# Previously there was a refcounting bug there, similar to the
# one described in inlined_handlers.pm

use strict;
use warnings FATAL => 'all';

use Apache2::RequestIO ();
use Apache2::ServerUtil ();
use Apache2::Const -compile => qw(OK DECLINED);

our $answer = "not ok 1\n";

sub test_waz_zere {
    my ($r) = @_;
    $r->notes->set("test_waz_zere", 1);
    Apache2::Const::DECLINED;
}

BEGIN { if ($ENV{MOD_PERL}) {
## This works (non-inlined handler):
#    Apache2->server->push_handlers(PerlFixupHandler => \&test_waz_zere );
## This did not work as of Subversion r159573:
    Apache2::ServerUtil->server->push_handlers(PerlFixupHandler => 
                                               sub { test_waz_zere(@_) });
} }

sub handler {
    my $r = shift;

    $r->print("1..1\n");
    $r->print($r->notes->get("test_waz_zere") ? "ok 1\n" :
             "not ok 1\n");
    Apache2::Const::OK;
}

1;
