hi,
I have a shiny new install barely 2 weeks old and I just caught bug
https://bugs.gentoo.org/show_bug.cgi?id=603798
so I have a broken
sys-devel/gcc-5.4.0-r1
and need to go back to a working one
I have
Code:
gcc-config -l
 [1] x86_64-pc-linux-gnu-5.4.0 *

so from what I gathered
https://forums.gentoo.org/viewtopic-t-801985-highlight-gcc+broken.html
the easiest way should be to unpack a binary from https://tinderbox.dev.gentoo.org
like this one for me
https://tinderbox.dev.gentoo.org/default-linux/amd64/sys-devel/gcc-4.8.3.tbz2

and do
Code:

wget -c https://tinderbox.dev.gentoo.org/default-linux/amd64/sys-devel/gcc-4.8.3.tbz2
tar -xjpf gcc-4.8.4.tbz2 -C /
env-update && source /etc/profile

then set my gcc with
gcc-config

then re-emergeing gcc-5.4.0 should be enough

What do you think?
do I get it right?

some later comments (11 is same as 4 but more detailed) in the bug might save you some effort .. a few edits and file copies and you should be able to recover..

thanks
I am following your suggestion and the path led by Holger Hoffstätte &Gary E. Miller
Code:


cd /etc/env.d/gcc
cp x86_64-pc-linux-gnu-5.4.0 x86_64-pc-linux-gnu-5.4.1

vi config-x86_64-pc-linux-gnu x86_64-pc-linux-gnu-5.4.1
#in vi change every 5.4.0 to 5.4.1 in the above 2 files --

cp /usr/lib64/gcc/x86_64-pc-linux-gnu/5.4.0/libgcc_s.so /usr/lib64/gcc/x86_64-pc-linux-gnu/5.4.1/libgcc_s.so
cp /usr/lib64/gcc/x86_64-pc-linux-gnu/5.4.0/libstdc++.so /usr/lib64/gcc/x86_64-pc-linux-gnu/5.4.1/libstdc++.so

compiling gcc now fingers crossed
edit:so far so good seems to have worked
