--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

clang rejects it:
<source>:2:26: error: attribute 'assume' cannot be used as an attribute pack
    [[assume(args > 0)...]];
                         ^

While MSVC accepts it.

I am not sure if it is this is valid or not but GCC should NOT be ICEing ei=
ther
way.=
