What's the version of g++ ?

Changing numpy version is unlikely to fix anything here, as the error is 
a crash from the C++ compiler.

One solution would be to update gcc (by compiling your own version), or 
more simply, if you don't need scipy.sparse to disable it in 
scipy/setup.py by commenting the sparse line.
