Evaluating constraints on an NTTP with a default template argument leads to a crash #84052
Description
https://godbolt.org/z/fY9Tevv89
sorry i cant think of meaningful title for below code
-std=c++26
template<class...>concept Invokable = true;
struct A {};
template<class T, Invokable<bool(const T)> auto = A{}>
struct Set{};
template<class T>
void asdf()
{
using A = Set<T>;
}
int main()
{
using A = Set<bool>;
}PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
