Consider the example of the problem report
1 template <typename>
2 constexpr bool the_truth () { return true; }
3
4 template <bool>
5 struct Takes_bool { };
6
7 template<bool B>
8 using Alias = Takes_bool<B>;
9
10 template<typename T>
11 struct test { using type = Alias<the_truth<T>()>; };
12
13 int main () {
14 test<int> a;
15
16 return 0;
17 }
that yields the error:
test.cc: In substitution of ‘template<bool B> using Alias = Takes_bool<B> [with bool B = the_truth<int>()]’:
test.cc:11:51: required from ‘struct test<int>’
test.cc:14:13: required from here
test.cc:11:51: error: integral expression ‘the_truth<int>()’ is not constant
struct test { using type = Alias<the_truth<T>()>; };
I think the issue happens in the course of instantiating test<int> at
line 14, when we look into instantiating Alias<the_truth<T>()> (at
line 11) (using instantiate_alias_template) with T = int.
There, when we check the argument 'the_truth<int>()' to see if it
actually is a constant expression, in check_instantiated_arg, we fail
to recognize it constexpr-ness b/c we just look at its TREE_CONSTANT.
At that point, the_truth<int> should have been folded, and it's not,
because instantiate_alias_template forgets to call
coerce_template_parms on its arguments.
Fixed thus, bootstapped and tested on x86_64-unknown-linux-gnu against
trunk.
