>Description:
Following code:

#include <cstdlib>
#include <xmmintrin.h>


int main(int argc, char * argv[])
{
   return 0;
}

compiles finely with this command:
g++ test.cpp

but fails with this:
g++ -pedantic test.cpp

The error is:

In file included from /usr/include/xmmintrin.h:42,
                 from tm.cpp:2:
/usr/include/mm_malloc.h:37: error: declaration of 'int posix_memalign(void**, size_t, size_t) throw ()' throws different exceptions
/usr/include/stdlib.h:160: error: from previous declaration 'int posix_memalign(void**, size_t, size_t)'
>How-To-Repeat:
Compile testcase from description with -pedantic flag.
