--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The error is now:
<source>:4:19: error: no matching function for call to 'foo(int [2147483648])'
4 | auto x = foo(a);
| ^
<source>:3:48: note: candidate: 'template<class T, long long unsigned int N> T*
foo(T (&)[N])'
3 | template<class T, unsigned long long N> T* foo(T(&t)[N]) {return
t;}
| ^~~
<source>:3:48: note: template argument deduction/substitution failed:
<source>: In substitution of 'template<class T, long long unsigned int N> T*
foo(T (&)[N]) [with T = int; long long unsigned int N = 18446744071562067968]':

But still emitted twice but then again MSVC also emits the error message twice
too:
<source>(2): error C2148: total size of array must not exceed 0x7fffffff bytes
<source>(2): error C2148: total size of array must not exceed 0x7fffffff bytes
