[Bug middle-end/17126] [3.5 Regression] ICE with -fno-unit-at-a-time and -O3

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The testcases in comment #11 and #8 do not fail any more.
However, the original testcase still fails.
Here's a reduced testcase for this failure:

==================================
void foo()
{
    struct { int i; } *p;
    p->i = 0;
}

void bar()
{
    foo();
}

void baz()
{
    bar();
}
==================================

Compiling this with "gcc -fno-unit-at-a-time -O3" causes an ICE:

PR17126B.c:15: error: Inlined_to pointer is wrong
foo/11: (inline copy in baz/9) 1 insns tree inlinable asm_written
  called by: bar/10 (inlined) 
  calls: 
PR17126B.c:15: internal compiler error: verify_cgraph_node failed.
Please submit a full bug report, [etc.]
