Rakudo r35994:

$ cat B.pm
class B;
$ perl6 -e 'use B; class A { method a { my $e = B.new() } }; A.new.a'
$ perl6 -e 'class A { use B; method a { my $e = B.new() } }; A.new.a'
Null PMC access in find_method()
[...]

The fact that B is declared with the semicolon form is irrelevant --
C<B {}> produces the same error.
