Hi Tom I shall put together the full list of stuff you mentioned, but 3 quick things 1) the system apparently does support SSE (see below) 2) we have a few custom C++ blocks in the app, perhaps there's some rule we're breaking and so running afoul of the SSE instruction operand alignment restrictions (is this possible?) 3) the problem is happening in a relatively complex GR app [http://op25.osmocom.org/wiki/wiki/SignalScopePage , using audio-IF mode]. Both 2 and 3 point toward the need to try to reproduce the problem here with a simplified test app, finding the absolute minimum number of GR blocks needed to do so, and ruling out the possibility that's it's something we're doing wrong...
