Whoops yourself. The following patch brings your example into line with
the driver code. mpuout is a pointer to a structure not the structure itself
as the malloc assignment clearly indicates.

*** 2,8 ****


struct foo { int a; int b; };
! struct { struct foo foo; } *foobar;

int main (void)
{
--- 2,8 ----


struct foo { int a; int b; };
! struct { struct foo *foo; } *foobar;

int main (void)
{

Now Prints:

8
