Hi Maxim, Very strange. The threading part of osgViewer hasn't changed, and OpenThreads under Linux hasn't changed, I don't think there is any recent changes on the OSG side that might have introduced problems. Doing the exactly same test on my system doesn't result in any problems.
My best guess is that there is some driver issue on your system which is causing a failure to create the required graphics context. As I suggest before getting a strack and looking at where the crash happens might provide some clues.
