Hi Benjamin,

LD_PRELOAD cannot be preloaded: ignored.

It might be a good idea to disable Steam's game overlay, just to be sure
it's not interfering with apitrace, as described in
https://github.com/apitrace/apitrace/wiki/Steam#linux , the " Otherwise, I
think what you're doing should be fine.

For these warnings I'll push a fix to apitrace shortly, but they are
harmless -- it won't affect the trace at all.
