Bug ID: 99387
Summary: ICE when mixing CNTTP with deduction guides
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: omer.rosler at gmail dot com
Target Milestone: ---
https://godbolt.org/z/n55re3
This code causes an ICE (while clang rejects it).
Changing line 21 to `template<auto templ>` causes a deduction failure (which is
wrong).

Confirmed. The ICE started with r11-2015, and then r11-6816 turned it into
another ICE.
Never worked so not a regression. But if the fix is for C++20-only paths, we
could still go and fix it.

Reduced:
template <auto> struct A { };
template <class> struct B { };
template<template <class> class Tmpl, Tmpl V>
void f (A<V>);
int main() {
A<B<int>{}> x;
f(x);
}

--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
This PR seems to have been fixed by r12-6773:
commit 09845ad7569bac27c3a1dc7b410d9df764d2ca06
Author: Patrick Palka <ppalka@redhat.com>
Date: Thu Jan 20 09:25:49 2022 -0500
c++: CTAD inside alias template [PR91911, PR103672]
Note the Comment 1 test now compiles fine too. clang++ rejects Comment 3 too.
