DEBUG=on enables a lot of runtime checks poorly tested on FreeBSD. Better use just debugging symbols (see below). If the stack trace isn't complete rebuild 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 += OPTIMIZED_CFLAGS CFLAGS += -g STRIP = # 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=<optimized out>, uv_off=<optimized out>, y_off=<optimized out>, ctx=<optimized out>) at libavcodec/vp9.c:2719 #2 intra_recon_8bpp (ctx=<optimized out>, y_off=<optimized out>, uv_off=32) at libavcodec/vp9.c:2761 #3 0x000000082b24830c in decode_b (ctx=0x826645120, row=0, col=8, lflvl=0x825e36960, yoff=64, uvoff=32, bl=BL_64X64, bp=PARTITION_NONE) at libavcodec/vp9.c:3324 #4 0x000000082b24f19b in decode_sb (ctx=0x826645120, row=0, col=8, lflvl=0x825e36960, yoff=64, uvoff=32, bl=BL_64X64) at libavcodec/vp9.c:3428 #5 0x000000082b25ac44 in vp9_decode_frame (ctx=0x826645120, frame=0x826882420, got_frame=0x82cbdd4d0, pkt=0x82cbdd468) at libavcodec/vp9.c:4181 #6 0x000000082b08f225 in frame_worker_thread (arg=<optimized out>) at libavcodec/pthread_frame.c:161 #7 0x0000000801c58dc4 in ??
