True. It might not crash in the same way as when I use the package's
irrecord with the package's libirrecord.so library. I'm done chasing it

Right. The default configuration and the official guidelines don't work.
* I used the devinput.lircd.conf provided by the package, together with
driver = devinput and my remote wouldn't work.
* I ran lirc-make-devinput as recommended by irrecord to generate a new
devinput.lircd.conf file, still using driver=devinput, and the remote
still wouldn't work.
* Seconds after I regenerated the devinput.lircd.conf with
lirc-make-devinput, lircd complained that it is outdated:
Sep 24 01:33:47 habsheim lircd: lircd-0.10.0: Warning: Obsolete devinput config file used
Sep 24 01:33:47 habsheim lircd: lircd-0.10.0: Notice: Use the distributed devinput.lircd.dist by renaming it.
Sep 24 01:33:47 habsheim lircd: lircd-0.10.0: Notice: Or use irdb-get to search for "devinput" and download it.
* With both versions of the devinput.lircd.conf lircd complained that
all buttons were duplicated, which makes sense since they appear in
both the devinput-32 and devinput-64 remotes.
Sep 24 01:11:43 habsheim lircd: lircd-0.10.0: Notice: /etc/lirc/lircd.conf.d/devinput.lircd.conf: devinput-64: Multiple values for same code: BTN_MISC
Sep 24 01:11:43 habsheim lircd: lircd-0.10.0: Notice: /etc/lirc/lircd.conf.d/devinput.lircd.conf: devinput-64: Multiple values for same code: BTN_MOUSE
* Now I finally got the remote to work with the default driver (i.e. not
devinput (despite it being the default driver)) but I had to recreate
the remote configuration file from scratch as the one I used with lirc
0.9.4c wouldn't work. The official guidelines don't talk about that
* Oh, and for the remote configuration files comment lines must have a
'#' in the first column. Put spaces before and the configuration file
breaks. If that's documented somewhere then I did not find where.
So crashes in irrecord? No one will notice that bit of brittleness.
