I'm seeing the same issue with 4.9.2 and bootstrap-lto.
Trying to compile with binutils 2.24 (self built), gcc-4.9.2 on Fedora 20 (gcc
version 4.8.3 20140911 (Red Hat 4.8.3-7) (GCC)) (based on compile script here:
http://joelinoff.com/blog/?p=1604#more-1604)
Configure:
configure --disable-cloog-version-check --disable-ppl-version-check
--enable-cloog-backend=isl --enable-gold=default --enable-languages=c,c++
--enable-lto --enable-libssp --enable-plugins --enable-plugin
--disable-multilib --with-build-config=bootstrap-lto
--prefix=/home/jacek.sieka/Downloads/rtf
