I'm attempting to build GCC (current git master) but am running into a

I'm configuring using:
./gcc-git/configure --prefix=/home/abenson--enable-languages=c,c++,fortran --
disable-multilib
which appears to succeed. Then running make eventually gives

Using "git bisect" shows that the first bad commit causing this problem is:
https://gcc.gnu.org/git/?
p=gcc.git;a=commit;h=a68412117fa47786bd82ab79b009ec7933aef476
Has any one else found this problem, or know how to work around it?
Note that you're actually getting a segfault in the linker which is part
of the binutils project. While the compiler might be generating
something the linker dislikes, the linker shouldn't be segfaulting.
