Hi Moritz, thanks for the report.

As for apitrace: In case you're running via Steam, consult this page:
https://github.com/apitrace/apitrace/wiki/Steam - I've generally been
successful with the instructions there.

As to the bug itself: The immediate reason for the crash seems apparent enough:
we fail to map the buffer into which query results are written. That code needs
to be hardened, and I've added that on my todo list.

However, we shouldn't fail that map in the first place. So an apitrace would
indeed be helpful to understand better what's really going on here... do you
have any other output from before the crash?
