Actually it's the -f option that causes the crash. I can reproduce it
with:
# irrecord -f /tmp/foo.conf
This would just indicate that foo.conf is broken somehow. Given the
state of lirc, I don't think it's feasible to make it handle any kind of
broken input files - it's just too fragile.
But it's not 100% reproducible now, particularly when I try to use
my own libirrecord.so so I have debugging symbols. What I can give you
though is the irrecord backtrace:

Compiled from git commit be62884be227.
So the crash happens somewhere in record_buttons() in irrecord.c.
I suspect the curr_driver methods are not getting initialized...
sometimes.
Thanks. That said, if this from a version you compiled yourself, the
libirrecord.so seems to be the wrong one (i. e., the one installed by
the package). This will by definition be unstable - the libirrecord ABI
being part of lirc_private.h is not supposed to be the same between
versions.
Now as to why I have driver=devinput in lirc_options.conf, it's because
it's the only way I found to get my remote to work. Setting
driver=default driver does not work and if I only provide
devinput.lircd.conf and no Hauppauge_PVR350.conf file then it does not
work either.
I think you really need to take a step back here. The way you use lirc
does not match the official guidelines in [1], which you probably need
to check. In short:
- As mentioned in the irrecord message the way to update
devinput.lircd.conf is the lirc-make-devinput(1) script, not irrecord.
- Use mode2(1) to check if you get something sane using the devinput
and/or the default driver.
- If you go with the devinput driver, use devinput.lircd.conf. In a
off-the-shelf setup, just copy it into /etc/lirc/lircd.conf.d. Check
that /etc/lircd.conf does nothing but include the files in lircd.conf.d.
- If you go with the default driver, you might very well need to use
irrecord with this driver. Copy the generated file into lircd.conf.d.
- In any case, don't use irrecord with the devinput driver since this
is not a supported usecase.
- When running into problems, raise the loglevel and submit the
console logs.
IMHO, this is now more of a support issue than a bug report.
Cheers!
