I'm assuming Jordan can coordinate that with Valve. Afaics he is the one
assigned for the issue over at github.

Those should be harmless, as steam LD_PRELOADs a bunch of libraries. Afaik
steam is 32bit, while Vedran was running a 64bit system - thus the messages. 

There are a couple of other interesting bits in the log:
 - Alarming heap stats (allocated ~770 MiB, in-use at exit ~220MiB)
 - Invalid memory access in various modules - invalid reads in various steam
runtime components, alarming number of invalid writes in i965_dri.so.

The latter one perhaps should be looked into closer ?

> Please if someone knows any Steam devs CC them here?
Afaict unless a person is known* by bugzilla one cannot CC them. For example
one cannot CC your @intel email, so I've opted for the known @linux.intel one.
