[Bug c/26732] New: Rejects valid code at different optimization levels.

["ramana dot radhakrishnan at codito dot com" <gcc-bugzilla at gcc dot gnu dot org>]

#include <stdlib.h>
int
bar(baz)
struct { int foo; } baz;
{
        return baz.foo;
}

int main (void)
{
        struct { int foo; } baz;
        baz.foo = 0xdeadbeef;
        if (bar(baz) != 0xdeadbeef)
          abort();
}

Compiling at O2 results in no error. 
compiling at O3 results in the following error :
 fail.c:35: error: incompatible type for argument 1 of 'bar'

This is a regression from 3.4.x .Have not checked this for mainline yet.
