May be related to #44900.

CC @aclements @dr2chase for regabi. (I'm not sure who else is working on that set of changes..?)

These are known and fixed (due to inconsistency in enabling regabi).

These are also known and fixed (broken by a CL of mine).

It seems the rest are all ARM or Solaris.

Is this issue still actionable for Go 1.17, or is this better covered by other regabi issues, or should we move this to Backlog?

A lot has changed for regabi, and the original bad pointer issue is fixed.

There are other failures mentioned above, like the ARM ones and Solaris ones. But they are not regabi related.

The Solaris failures are tracked by #44902.

The Plan9 failures are tracked by #46822.
