Bug ID: 96097
Summary: ICE in dependent_type_p, at cp/pt.c:26326
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bruck.michael at gmail dot com
Target Milestone: ---
https://gcc.godbolt.org/z/WVUAy5
Same error location as PR95931, but very different test case with valid code
(probably).
<source>: In function 'void test()':
<source>:17:22: internal compiler error: in dependent_type_p, at cp/pt.c:26343
17 | func<Y<X, 0>, Y>();
| ^
Fails with -std=c++17 at least since gcc5.1
---
template <
typename A,
template <typename T, typename T::typeX> typename TA>
auto func()
{
return TA<typename A::typeY, 0>{};
}
struct X { using typeX = int; };
template <typename T, int>
// template <typename T, typename T::typeX> // works
struct Y { using typeY = T; };
void test()
{
func<Y<X, 0>, Y>();
}

Confirmed, clang accepts the code. GCC ICEs for all revisions.

Hi,
I just realized I have reported an ice-on-invalid version in bug 95931 with the
same symptom in the trunk. Maybe you can consider them together.
Thanks,
Haoxin

Looks like a dup of bug 90782.

Further simplified code
template <template <typename T, typename T::type> typename>
void func() {}
template <typename, int>
struct Y {};
void test()
{
func<Y>();
}

--- Comment #8 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Here, make_typename_type is called when tsubsting, i.e. p_t_d is 0, and it
calls dependent_scope_p with a dependent type. We might need ++ptd/--ptd
around the call to make_typename_type.
