I confirm this ICE with the patch and will provide a smaller test case soon.

--- Comment #3 from Paul Waring <paul at xk7 dot net> ---
I can confirm the same issue occurs for me on OS X  10.10 (Yosemite) and the
following:

GCC: 4.9.2
binutils: 2.25
MPFR: 3.1.2
MPC: 1.0.3
GMP: 6.0.0a
Newlib: 2.2.0-1

clang --version
Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin14.3.0
Thread model: posix

Is there anything I can do to help fix this bug?
