--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
This works with ISL in my source tree (the --disable-werror option suppresses
build failures due to -Wuninitialized):
$ /src/gcc/trunk/configure --enable-languages=c,c++,fortran,go,lto,obj-c++
--enable-checking=release --disable-werror
...
$ make -j10 profiledbootstrap
What seems to break it is the -flto option in BOOT_CFLAGS. That's also
supported by Jakub having used profiledbootstrap regularly over the last months
but without LTO.
