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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
