Noting the same bug upon receiving an invite:
Gentoo ~AMD64 fully up to date
Same segfault. Happened as soon as a friend messaged me.
Arch Linux x86_64 with 361.18 drivers. Everything is up to date, I'm on the beta client.
same for me in gentoo ~amd64 and most of steamlib disabled.
And it almost always happens if i get an invitation in dota2 - while dota is running.
I am using nouveau so its not related to graphics driver.
Similar issue here.
It's most likely related to sound for my case, as:
_ everything was fine until I started to try to combine nVidia-HDMI & motherboard outputs
_ it complains about not being able to load "default" in "OAL" (OpenAL ?) device.
As for "braindevices", it seems sound-related.
Reading "OrdinaryMagician", it actually makes sense with the friend message as it probably triggers a sound.
Here is a sample taken around the end of /tmp/dumps/MYLOGIN_stdout.txt

It crashes in a few minutes. If fixing the audio fixes this, then it's probably the culprit. (For my case anyway).
Nothing extracted yet.
after latest upgrading of the steam client. It starts these random segfault.
in steam:
