The test passes again (rakudo-j). I'm closing this ticket as resolved.

This test now dies on the JVM with a java.lang.StackOverflowError

re-opening ticket.

The Null PMC access is gone, so I'm closing this ticket.

The error message has changed slightly:

$ perl6-m -e 'my ::foo $x; say $x'
Cannot type check against type variable foo
  in any type_check at src/gen/m-Metamodel.nqp:297
  in block  at -e:1

I added a test for this exception to S02-names-vars/names.t with commit 
https://github.com/perl6/roast/commit/5e0641d092

If you don't think current behaviour is correct, please reopen the ticket.

Also, there was another Ticket (#72814; with test in S04-declarations/my.t) 
about the Null PMC access with 'my ::foo $x;'. I'm gonna merge both tickets.

Now they say:

00:19 < [Coke]> rakudo: my ::foo $x; say $x
00:19 <+p6eval> rakudo cbdd9b: OUTPUT«Cannot call a method on type variable 
foo␤  in

00:19 < [Coke]> rakudo: my ::foo $x;
00:19 <+p6eval> rakudo cbdd9b:  ( no output )
00:19 < [Coke]> rakudo: my ::foo $x; say "alive"
00:19 <+p6eval> rakudo cbdd9b: OUTPUT«alive␤»
