Bug#853287: Acknowledgement (gcc-6 ICE: in output_index_string,, at dwarf2out.c:25635 (reported upstream 70578))
It seems that combining -g3 and -gsplit-dwarf is the root cause for MY
problem.
Even gcc experiences an ICE.
/usr/bin/gcc-5 -std=gnu99 -o vp9_dsubexp.o -c -DNDEBUG=1 -DTRIMMED=1
-DHAVE_CONFIG_H=vpx_config.h -fPIC -DMOZILLA_CLIENT
-fno-builtin-strlen -Wl,--gdb-index -Dfdatasync=fdatasync
-DDEBUG_4GB_CHECK -DUSEHELGRIND=1 -gsplit-dwarf -g3 -Og
./vp9_dsubexp.i
/new-hd1/extra/ishikawa/TB-3HG/NEW-COMMSRC/mozilla/media/libvpx/libvpx/vp9/decoder/vp9_dsubexp.c:72:1:
