[Nicholas Savenlid]

Opening properties on a pin works fine, closing the property dialog gives a crash.

the footprint file

[jean-pierre charras (jp-charras)]

Some comments (Windows Build):
It happens only in GAL mode.
Editing a pad from the board editor does not create this issue.
This issue is reproducible when importing a footprint from the footprint editor.

When Kicad is built in debug mode, the crash is immediate when trying to edit a pad in the fp editor, whenever the footprint.
gdb crashes when trying to get the backtrace.

[Maciej Suminski (orsonmmz)]

It is one of the strangest bugs I have ever seen. As far as I can tell, the most reliable way to reproduce it is to change a pad width to make it ~2x bigger than its length and apply the change. Happens only with Windows, so we are left with crappy debugging tools. Bisecting..
