```
class C {
    template <typename T>
    void operator delete(void* ptr, T user) {}
};
template void C::operator delete<float>(void* ptr, float user);
```

Confirmed not a regression has been ICEing since at least 4.1.2.

--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So I looked and found that this was reported before but the bug which it was
reported on was closed as fixed as the original testcase in that bug was fixed.
See bug 36406 comment #2 for the testcase which fails still after the fix for
that bug report.
