When I try to upgrade a multilib gcc, it seems it is installing the new 32 bit libs, then removing all the old libs (32 and 64 bit), then trying to install the new 64 bit libs but fails because there are no 64 bit gc libs on the system (see build.log). Afterwards you cannot run any executables and you have no working compiler. The only way to recover the system is to restore the old gcc files from a backup.

Steps to Reproduce: 1. emerge '=sys-devel/gcc-4.8.4' 2. echo '=sys-devel/gcc-4.8.5::gentoo abi_x86_32 abi_x86_84' >> /etc/portage/package.use 3. emerge '=sys-devel/gcc-4.8.5' Sorry.
are you sure the package.use setting matters ? gcc shouldn't be checking those flags currently. you can check the file type by doing: find /usr/lib/gcc/x86_64-pc-linux-gnu/ -exec file -L {} +
I'm sorry, I was mislead by the 32bit files having a /32 subdir, while the 64 bit libs not. I tried it again, the files are all there, they are just not found. In a shell "source /etc/profile" fixes the problem. Also, autoclean seems to have succeeded, as the old libs were gone. I dont know why postinst fails, maybe it tries to execute some programs without doing an equivalent of "source /etc/profile" after the old libs are already gone.
it might be related to bug 529608. but with that fix and all the multislot logic shaking out, i'd say this has just resolved itself unless you can show that it's still happening. i.e. try to do: - install gcc-4.9.3 - remove all other versions - upgrade to gcc-5.3.0 - see if you get libgcc_s.so.1 errors
