libstdc++ versus -Wcast-align

[Benjamin Kosnik]

You can try adding

#pragma GCC system_header

to bits/stl_alloc.h, which might hide this error.

You could try using a different allocator than the default __pool_alloc.

The other option would be to properly align allocated memory. 

So

516:
          __next_obj = (_Obj*)((char*)__next_obj + __n);

probably comes from:

456:
          _S_start_free = (char*) __new_alloc::allocate(__bytes_to_get);


You'll need to figure out how to align this.
