我最近从http://hpc.sourceforge.net/安装了gcc，而其他一切正常，每当我尝试在标头中包含cmath时它会显示以下错误：
/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__;

g++: internal compiler error: Abort trap: 6 (program cc1plus)

我正在使用OSX Yosemite并在输入gcc -v时显示以下内容：
