Description sphakka 2020-06-16 12:22:29 UTC

sys-apps/kbd-2.2.0-r2 ships a broken `dumpkeys` which crashes when just calling it like this:

   # dumpkeys
   ...
   string Pause = "\033[P"
   Segmentation fault


This also causes some (minor?) breakage at boot time (openrc):

  * Saving key mapping ...
  /etc/init.d/save-keymaps: line 20:  2320 Segmentation fault      dumpkeys > "$RC_LIBEXECDIR"/console/keymap
  * Unable to save keymapping 
   

It used to be good with `sys-apps/kbd-2.0.4`...

Could you please capture a backtrace using gdb?

I'm unable to reproduce this locally.

Do you have a non-default keymap loaded when you run dumpkeys?

Oops, yes, I forgot to mention! It seems to load correctly at boot.
