Comment(by k...@…):
The only things I've built with 4.5 are kernels, but looking at my full
logs from the last system build (LFS-6.6) the following used -Os :
grub-1.97.2, cups, firefox (I think the latter because BLFS has --enable-
optimize).
If I was a betting man, I'd put (a little) money on it only being x86_64
*and* only likely to show up in the kernel. I know firefox would be easy
to change if it too shows the problem (--enable-optimize=-O2). For
cups-1.4.3 I'm less sure, but I think it can be overridden --with-
optim=-O2.
If you can confirm that the grub built by 4.5 on x86_64 is good, I suggest
putting a warning for x86_64 on the kernel. If it does bite people on
cups or firefox, we can put notes in the BLFS wiki until BLFS moves beyond
6.5,
