--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Tried e.g.
-std=c++11 -fPIC -g -mbackchain pr124135.C -fstack-protector-strong -Wformat
-Werror=format-security -fno-stack-clash-protection
(what I saw in the build log) with -O{0,2} and -march={z10,z13,z14,z15} or even
-m31 and nothing ICEs (in a cross though).
