[Discuss-gnuradio] seg fault in volk_32f_s32f_multiply_32f_a_sse gnuradi

From: ikjtel
Subject: [Discuss-gnuradio] seg fault in volk_32f_s32f_multiply_32f_a_sse gnuradio v 3.6.1
Date: Fri, 24 Aug 2012 15:33:22 -0700 (PDT)

At the moment it's easily reproducible.  Same app runs under GR v3.3 with no trouble. Let me know if I can provide any more info - in particular, perhaps there's a special GDB command to dump the "xmm" register set?

Best Regards
