RFR(XS) 8029446: assert(_cfg.get_block_for_node(proj) == borig) failed: incorrect block for kill projections

Why is it AMD64 only?  Can you please add the investigation to the bug report as well?

When cloning it, we also want to clone its kill projection node (if any) and we check that the kill projection node is in the same block as the loadConP0 node. The problem is that the kill projection node is never added to the loadConP0 node's block when it is created so we end up failing the assert.
