First I like to say this is violating C++ aliasing rules but that is a
different story.
Second this is most likely a dup of bug 28479.

Are you sure you got that bug number right? I'm seeing this ICE not just with
current 4.2 but also from many months ago (will try to narrow down a date in a
minute).

Oh, yes it is unrelated to that PR. In fact I think the aliasing violating
causes the problem.

Even without the volatile, it ICEs:
typedef unsigned long int ulong;
typedef struct
{
int counter;
}atomic_t;
static ulong Cversion = 0;
void
sp_cache_invalidate ()
{
atomic_t * v1 = (atomic_t *)& Cversion;

I can trivially fix this, but the code isn't going to do what you want when i'm
done, since it is an aliasing violation :)
The assert in question just happens to be good at catching them.

------- Comment #20 from mmitchel at gcc dot gnu dot org 2007-02-19 23:33 -------
Is there a backport of the mainline patch that I could review, or ask another
maintainer to review for inclusion in 4.2?
Thanks,

The attached patch named "access_debugging.diff" should apply and work for 4.2.
