I am quite sure, see
http://autobuild.buildroot.org/results/09b/09b08d329e632365dd8371371706dbeaa10539a3/build-end.log:

libavcodec/dpxenc.c: In function 'encode_frame':
libavcodec/dpxenc.c:162:1: internal compiler error: in
elimination_costs_in_insn, at reload1.c:3638

The toolchain, available at
http://autobuild.buildroot.org/toolchains/tarballs/br-sh4-full-2015.05-496-g85945aa.tar.bz2,
uses gcc 4.9.3.
