Running this with --ll-exception reveals it as an optimizer bug​:

Cannot find method 'orig'
  at src/gen/m-Perl6-Optimizer.nqp​:296 (./blib/Perl6/Optimizer.moarvm​:add_exception​:18)
from src/gen/m-Perl6-Optimizer.nqp​:1452 (./blib/Perl6/Optimizer.moarvm​:optimize_private_method_call​:228)
from src/gen/m-Perl6-Optimizer.nqp​:1157 (./blib/Perl6/Optimizer.moarvm​:visit_op​:1133)

This is the code that dies​:

  method add_exception(@​name, $op, *%opts) {
  %opts<line> := HLL​::Compiler.lineof($op.node.orig, $op.node.from, :cache(1));
  %opts<modules> := $*W.p6ize_recursive(@​*MODULES);

Seems $op has no .node set.

Fixed in commit 43a2cee, test added here​: Raku/roast@7502f61542
