DEBUG=3Don enables a lot of runtime checks poorly tested on FreeBSD. Better= use just debugging symbols (see below). If the stack trace isn't complete rebui= ld every package firefox depends. Note, you may need to hack some ports (e.g. multimedia/ffmpeg) that don't respect STRIP variable in order to disable stripping without turning off optimized assembly. # Put into /etc/make.conf or /usr/ports/www/firefox/Makefile.local OPTIONS_UNSET +=3D OPTIMIZED_CFLAGS CFLAGS +=3D -g STRIP =3D # empty Here's what I get after rebuilding just multimedia/ffmpeg and www/firefox: (gdb) bt #0 0x000000082b3b2330 in ff_vp9_ipred_dc_left_32x32_avx2 () from /usr/local/lib/libavcodec.so.56 #1 0x000000082b214f2a in intra_recon (bytesperpixel=3D<optimized out>, uv_off=3D<optimized out>, y_off=3D<optimized out>, ctx=3D<optimized out>) at libavcodec/vp9.c:2= 719 #2 intra_recon_8bpp (ctx=3D<optimized out>, y_off=3D<optimized out>, uv_= off=3D32) at libavcodec/vp9.c:2761 #3 0x000000082b24830c in decode_b (ctx=3D0x826645120, row=3D0, col=3D8, lflvl=3D0x825e36960, yoff=3D64, uvoff=3D32, bl=3DBL_64X64, bp=3DPARTITION_NONE) at libavcodec/vp9.c:3= 324 #4 0x000000082b24f19b in decode_sb (ctx=3D0x826645120, row=3D0, col=3D8, lflvl=3D0x825e36960, yoff=3D64, uvoff=3D32, bl=3DBL_64X64) at libavcodec/vp9.c:3428 #5 0x000000082b25ac44 in vp9_decode_frame (ctx=3D0x826645120, frame=3D0x826882420, got_frame=3D0x82cbdd4d0, pkt=3D0x82cbdd468) at libavcodec/vp9.c:4181 #6 0x000000082b08f225 in frame_worker_thread (arg=3D<optimized out>) at libavcodec/pthread_frame.c:161 #7 0x0000000801c58dc4 in ??
