Rakudo 087e299898416ca6c3a6e2b2bdc3785d841f0ec6​:
./perl6 -e 'class P { submethod BUILD($o) { say self.WHAT; $o.shout } };
class C is P { method shout { say "alive" } }; C.new()'
P
alive
C
alive

The submethod BUILD is called twice here, once for the parent and once
for the
child class. If the child class defines such a submethod itself, each is
only
called once and all is fine​:

$./perl6 -e 'class P { submethod BUILD($o) { say self.WHAT; $o.shout }
}; class C is P { submethod BUILD($o) { say "in child" }; method shout {
say "alive" } }; C.new()'
P
alive
in child
