I have encountered a few internal compiler errors with g++ when I have
asked it to optimise C++ programs which have included particularly
complex expressions. You could try setting the CXXFLAGS environment
variable to include -O0 to prevent g++ from attempting to optimise the code:

CXXFLAGS='-O0' mkoctfile hello.cc

You might also want to check the gcc bugs database and report the error
if it is not already included. Instructions are at
http://gcc.gnu.org/bugs.html
