Segfault crash immediately on spawn, any map; any mode

[AlonzoTG]

Hey, I'm on gentoo linux/ryzen (RMA'd week 32 part).

The first problem here is that there isn't enough information in this crash barf to isolate the location of a segfault to a specific file, ie system, steam, or portal. I understand that stack traces might be security sensitive in this project, but being able to isolate system issues could lead to a resolution without further pain.

The game has been played beginning to end on this machine/linux distribution before, before I bought the ryzen...

I have not done a complete OS installation on this system since 2010

Hello @AlonzoTG, this looks like a SIGSEGV in libc-2.25.so (glibc).
