Compiling C++ files when including cmath in header

I have recently installed gcc from http://hpc.sourceforge.net/ and while everything else works fine whenever I try to include cmath in the header it is showing the following error:

/usr/local/lib/gcc/x86_64-apple-darwin13.4.0/5.0.0/include-fixed/math.h:273:5: internal compiler error: Illegal instruction: 4
     return __inline_isfinitef(__x) && __builtin_fabsf(__x) >= __FLT_MIN__;
     ^

/usr/local/lib/gcc/x86_64-apple-darwin13.4.0/5.0.0/include-fixed/math.h:273:5: internal compiler error: Abort trap: 6
g++: internal compiler error: Abort trap: 6 (program cc1plus)
Abort trap: 6

I'm using OSX Yosemite and on typing gcc -v it shows the following:

Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-apple-darwin13.4.0/5.0.0/lto-wrapper
Target: x86_64-apple-darwin13.4.0
Configured with: ../gcc-5-20140928/configure --enable-languages=c++,fortran
Thread model: posix
gcc version 5.0.0 20140928 (experimental) (GCC)

Thanks in advance for your time.

Solution

This can happen when the GMP library was compiled for CPU which provides instructions not available on the runtime CPU, see gmp CPU identification
