I started trying to build the linux kernel with LTO, but quickly ran
into
% gcc45 -flto -O2 -nostdlib -r -o init/built-in.o init/main.o init/version.o
init/mounts.o init/initramfs.o init/calibrate.o
In function 'error':
lto1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
lto-wrapper: /usr/local/bin/gcc45 returned 1 exit status
collect2: lto-wrapper returned 1 exit status
Seems error itself is broken?
