It reproduces with > ../gcc/configure --enable-host-shared --enable-plugin > --with-build-config=bootstrap-lto-lean --enable-languages=c,c++ > make -j64 profiledbootstrap STAGE1_CFLAGS="-O2" BOOT_CFLAGS="-O2 > -D_FORTIFY_SOURCE=3 -fstack-protector-strong -funwind-tables > -fasynchronous-unwind-tables -fstack-clash-protection -g" some of the flags might not be necessary. Just --enable-plugin is not enough. I have an ltrans file that reproduces the ICE w/o any profile data and with lto1 that's not from the bootstrap. Will attach.
