What version of Go are you using (
Does this issue reproduce with the latest release?
What operating system and processor architecture are you using
What did you do?
Try to implement frame pointer unwinding for the tracer (gh 16638, wip patch).
What did you expect to see?
copystack should adjust frame pointers on the stack when growing the stack.
What did you see instead?
TODO what about arm64 frame pointer adjustment?
