Comment:

 This seems to be a rebirth of #2439 and #2476.

 I've just tested on trunk and on 7.0.3RC1 and I can confirm the following
 behaviours of g.gui.vdigit:

 1.

 * Digitize one straight line.
 * Digitize a second straight line that crosses the first
 * Hit undo

 => Segmentation fault

 2.

 * Digitize an area with the last line crossing the first
 * Undo

 => Segmentation fault


 3.

 * Digitize one straight line
 * Undo
 * Redo

 => Segmentation fault

 I also again can see the same issue discussed in #2439 concerning the
 dotted guiding line for digitization disappearing.

 I don't know when this all reappeared, but at the time I'd done some
 extensive testing and MarkusM's fixes worked for me. No idea why the issue
 is back.

 Declaring this as a blocker for 7.0.3 as this should just work, but could
 others test and confirm ?
