Is upstream aware of this problem? If so please provide link to the upstream bug here.
Created attachment 311317 [details, diff] Patch to ensure the loop only ever visits elements of the mouse_codes array Could you please test the following patch? It just changes the array boundaries of the for loop from size(mouse_codes) to 1, down to size(mouse_codes) - 1 to 0. If you need instructions as to how to apply it or anything, just let me know...
The patch works. I've compiled and tested xf86-input-wacom with -O3 and it's all good. Chí-Thanh, I haven't reported upstream.
Thanks for testing that, this has now been reported upstream as linuxwacom bug 3525615...
This should be fixed in 0.15.0, which is now in the tree. Please test this, and reopen the bug if you're still experiencing problems...
