Hi, I've attached a small test program extracted from multimedia/gstreamer-ffmpeg (libavcodec/h264_cabac.c:ff_h264_init_cabac_states(H264Context *h)).
When you compile and run it like this on FreeBSD/i386, it results in a SIGBUS: % cc -o paddd paddd.c -O3 -msse2 -fPIE -fomit-frame-pointer % ./paddd Bus error The reason is this instruction where %esp isn't 16-byte aligned: paddd (%esp), %xmm7 Is this an upstream bug or is this because of local changes (to make the stack 4 byte aligned by default or something)?
