--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a reduced testcase:
```
template<typename T, typename T1>=20
int f (T x, T1 y) throw ()
{
    return 3;
}

int
main ()
{
  return (f (0.0f64x, 0.0f64x) + f (0.0f64x, 0.0L)) !=3D 6;
}
```
This ICEs and with release checking it produces an assembler error:
```
/tmp/ccJDRaEi.s: Assembler messages:
/tmp/ccJDRaEi.s:93: Error: symbol `_Z1fIeeEiT_T0_' is already defined
```

I can only assume the issue is _Float64x is not treated the same as long do=
uble
for type comparison but is treated the same for mangling (which is why I ma=
rked
it as an ABI issue).=
