Both of these reported issues — that 'double' and the stack are only four-byte
aligned — are specified by the i386 Linux platform ABI, and changing it would
completely break binary compatibility. You can request additional alignment
for a struct using __attribute__((aligned)); there is nothing you can do to
request additional stack alignment.
