gdb backtrace

At the start of a mission XCom2 crashes the moment when the drop solders of cut
scene ends. It doesn't happen in all maps only in this one as far as I can
tell.

I'm running Ubuntu 16.04 on an skylake CPU with a R9 380X. The crash happens
with stock Ubuntu mesa (11.2) as well as with mesa git
(git160414232200.eeff133) from padoka PPA.  

I tried to create a apitrace, but for some reason I can not get XCom2 to start
with "apitrace trace" in front of it. Are there any apitrace ninja secrets to
tracing steam games ;-)? (The game is 64bit so thats not the problem).
