Accept. I somehow missed the email/PR while reading all the messages after a
conference.

This is ok as the variable is not allocated.

I believe this is wrong. The pointer "t" is not modified at all, only the
component "point" of the pointer target is.
That is: Modifying t%x and t%point is ok, but changing the assignment of the
pointer "t" itself is not allowed.
