pastebins are not stable.  Here is the issue:

It looks to me that your system headers are incompatible.  mm_malloc.h and
stdlib.h need to agree, this seems to be a likely bug in your system headers. 
This probably doesn't work:


$ cat > t.cc
#include <cstdlib>
#include <xmmintrin.h>
^D
$ gcc t.cc
