There was a problem hiding this comment.

What I did
Fixed the issue that was manifested in the snekmate test. This bug is reported in #4215
How I did it
The bug was caused by error in
stack_reorderfunction. The function depends on the order of each operand but since the order changes there is the possibility to move same stack operand twice. To fix this issue I kept the information where necessary operands on stack.How to verify it
The example from the issue does compile now.
