Re: xsrc/40242: xkb: Alternative layouts don't work due to groups "invented" by the server (on both native and pkgsrc xorg)

["Jared D. McNeill" <jmcneill%invisible.ca@localhost>]

The attached test application can reproduce the issue.

$ cc `pkg-config --cflags x11` pr40242.c -o pr40242 `pkg-config --libs x11`
$ ./pr40242 

XkbGetKeyboard(ff) returned 0x0
XkbGetKeyboard(bf) returned 0x7f7ffd308110

Cheers,
Jared
