When I looked at the test my attention was immediately drawn to the

const char* impossible = "impossible";
return impossible !=

I memory serves me, get_key() will return the address of string of
characters inside the the address space of the DLL. This address is
compared to the address of "impossible" which is an address inside the
address space of the calling mainline application. I could not and
cannot understand what is being tested here. Honestly, when I see this,
I felt it unproductive to continue. Given that EVERYONE has looked at
this and no one has seen any problem with it, I wondering if I'm missing
something really obvious and I would be grateful if anyone could explain
this to me.

On a different note, I would point out that this whole issue appeared
when support for visibility for gcc was introduced last year. This is
kind of suspicious to me. An interesting test would be to:

a) find a platform on which test_dll_exported fails
b) rebuild/test with out support for gcc visibility - (by removing
"visibility=default") the the command line. And see if the change.
