typedefs and alignment

[Dan Carpenter <error27@gmail.com>]

I've found an issue handling typedefs and alignment.  In the appended 
code sparse things 'ptr' has to be aligned so the size of 'bar' is 1024.
I haven't looked at how to fix this at all, I thought I would ask the
experts for hints first.

regards,

#include <stdio.h>

typedef struct aligned_struct {
	int a;
}  __attribute__ ((aligned(1024))) ali_t;

struct foo {
	int b;
	ali_t *ptr;
};

int mainx(void)
{
	struct foo bar;

	printf("%d\n", sizeof(bar));
	return 0;
}
