G30 A Dnnn probing point problem

Evaluated the latest Test branch Marlin by Rich Cattell. Weird things happen in G30 A. G29 probes the bed OK. Also the first iteration of G30 A probes bed around the probing points OK. But... the after the second iteration all probing points happen at MIN_X position (Y varies). Checked bed and min/max parameters many times. And these must be somewhat correct because G29 and the first run of G30 A goes just well. Because this is being used it must work but in my Rostock mini it does not. Probe bed radius is 60 and autolevel grid 15.

Anyone else experienced this issue?

Solution: fix memory violation in saved position subroutine. That probably causes many kinds of G30 issues (depending on which variables happens to be located after the array in question)
