Hi All,

Anyone using my PCB+GL branch from repo.or.cz might want to consider
updating. I have just pushed fixes into the patch stacks addressing two
crash bugs in the branch.

One bug related to computation of the board outline, where outline layer
geometry extending outside the PCB area could lead to a crash if no
distinct board outline was determined by the code. It is relatively
unlikely people hit this bug in general use, although I did, so perhaps
others will have too.

Another, potentially more serious bug related to my addition of support
for objects on solder-mask layers. The additional layers attached into
the "bottom" and "top" groups would result in the GTK layer preferences
page trying to access off the end of an array of GtkWidgets.

This would result in possible memory corruption (or at least use-after
free), when bringing up the PCB preferences window of the GTK HID. The
most reproducible action for triggering a crash was the delete layers,
load a new set of layer colours, then switch the active editing layer.

Kind regards,
