Hi,
I did see -frounding-math in the cmake output:

-- USING CXXFLAGS = '-O2 -arch x86_64  -frounding-math -fno-strict-aliasing
-g'

How do I fix the problem?

Crystal ball... You are using a Mac with a recent version of Xcode.
Adding -DCGAL_FPU_HAS_EXCESS_PRECISION to the CXXFLAGS may help, but the last person who asked said it wasn't enough.

Best option is to complain to Apple with a link to:
http://llvm.org/bugs/show_bug.cgi?id=8100
(your compiler is llvm-gcc)

Now the crystal ball is sometimes wrong...
