I am not sure, if this is a binutils bug, but with sys-devel/binutils-2.22-r1 it didn't show up.

So not sure if this is a real bug. It happened while building gcc. The gcc emerge finished ok.
I need the full build log

Only with > sys-devel/binutils-2.23.1 the segfault is present. Strange, double checked with binutils-2.22-r1 and same behaviour, so this is a gcc bug or what ever. The warning in the build.log says checksum differs. Changing Bug Headline to gcc.
Please compile gcc with debug information and enable core dumps on your system, such that you further debug using a core dump; both these are documented on http://www.gentoo.org/proj/en/qa/backtraces.xml Once you have a core dump of gcc failing, you can run: `gdb /var/tmp/portage/sys-devel/gcc-4.6.3/work/build/gcc/cc1plus --core=/path/to/core` where you replace /path/to/core by the path to the core file of the failing cc1plus process.
Can't see any segfault in the build log and it looks like it merge fine for you. The only thing i can think of is that one of the configure tests make it segfault and that is logged in grsec and that can be a bug or i should segfault for the test. So you need to look in one of the config.log's if you can find the segfault or you need to make a coredump.
