Can you provide the preprocessed source which you can get via the -save-temps
option. Also does using -fno-strict-aliasing fix the issue?

Yes, because the code is invalid, a *definition* of ABC and DEF is missing: add
const int X::ABC; const int X::DEF; after your declaration of X and things will
work.

My recent 2.6.21.6-rt21 kernel build for ARM dumps a NULL pointer dereference
exception due to a missing loop termination condition that was omitted by the
gcc 4.3.1 optimizer.
This happens in net/ipv4/inet_hashtables.c, in function
inet_lookup_listener_slow which is inlined by the optimizer

The bug was discovered using the line in the summary, but a reduced test case
also produces the ICE:
namespace N1
{
templateclass T bool foo(); }
}
int main()
{
decltype(N1::fooint) a;
}
I believe this is ice-on-valid since removing the template like so:
