Yes, looks like it. But it's an Atom, which might change things. I know we had some issues on Atom's before, but I thought that we worked them out. I'll be interested to see how cmake reports the architecture checks for VOLK here. > 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... > > Thanks > > Max Thanks. Not sure what to make of that, yet. What happens if you just have a sig_source_f->multiply_ff->null_sink?
