--- Comment #2 from Matthias Klose <doko at gcc dot gnu.org> --- maybe the changes from PR65787 are unrelated. Building a compiler which has -fstack-protector strong enabled by default. The crash goes away when I add -fno-stack-protector to AM_CFLAGS in libgo. So it should be reproducible by adding -fstack-protector strong to AM_CFLAGS in libgo. Don't know why this shows up only now, and on powerpc-linux-gnu only.
