Slightly more reduced -m32 -g -O2:
struct A
{
int foo () const;
int bar () const;
struct { int d; } a;
};
struct B
{
int foo ();
int bar ();

void
baz (A &x, B h)
{
for (int i; i < h.bar (); ++i)

{
int g = x.foo ();
int f = x.bar ();
int e = c[0] & 1;
d = e << 1 | g << 16 | f & 1;
c[j] = 0;
}
}

Ah, but that one has undefined behavior in it (uninitialized i and j).
This one doesn't - -g -O2 -m32 again:
struct A
{
int foo () const;
int bar () const;
int a;
};
struct B
{
int foo ();
int bar ();
};
int *c, d;
int
A::foo () const
{
int b = a >> 16;
return b;
}
int
A::bar () const
{
int b = a;
return b;
}
void
baz (A &x, B h, int i, int j)
{
for (; i < h.bar (); ++i)
for (; h.foo (); ++j)
{
int g = x.foo ();
int f = x.bar ();
int e = c[0] & 1;
d = (e << 1) | (g << 16) | (f & 1);
c[j] = 0;
}
}

Seems this is because invalid RTL sharing, debugging.
