It should be mangled, because there are still three different things
named 'i' declared in this program, and so

how about
extern "C" void abort();
extern "C" { static int i; }
int *p = &i;
int main()
{
int i;
{
extern int i;
i = 1;
*p = 2;
if (i == 2)
abort ();
}
return 0;
}
in this case, the

That should do it.

You would add a translation unit that says
int i;
or similar. It's not "main::i", it's "::i", because of [basic.link] paragraph
7:
When a block scope declaration of an entity with linkage is not found to refer
to

How do you define main"::"i? That is, how'd you make the testcase work from a
second translation unit if it would fail now?

This testcase is the same principle, but might use a different code path in the
compiler:
extern "C" void abort();
extern int *p;
int main()
{
extern int i;
i = 1;
*p = 2;
if (i == 2)
abort ();
return
