Not reproducible on my system. Any chance of running it under GDB to get a backtrace?

I can reproduce this. It only happens when I keep the mouse on top of the progress bar window. Cause seems to be bug with wxBusyCursor in wxWidgets 3.0.1.

I can replicate this issue on archlinux with wxgtk 3.0.1 with gtk2. I can even replicate this issue when using an empty sheet (if you are fast enough).

I forgot to note that I can not make this segfault happen on wxgtk 3.0.2 and I get the same backtrace as Henrik in #3.

[Karl Zeilhofer (zeilhofer)]

Pcbnew also crashes, when filling the polygons with the shortcut B and then hold the cursor over the progress bar.

[jean-pierre charras (jp-charras)]

Your version uses wxWidgets: Version 3.0.1.
wxWidgets: Version 3.0.1 has a known bug relative to the mouse cursor icon.
It was fixed in 3.0.2.

Therefore fixing this bug in Kicad can be made only to use wxWidgets 3.0.2 instead of 3.0.1 to build Kicad.

[Nick Østergaard (nickoe)]

@Jean-Pierre, would a won't fix status be appropriate on this?
