g++-11.0.0-alpha20200607 snapshot (g:f08995eefbf579acfe40f0204727d5ce388e3d0a)
ICEs when compiling the following testcase reduced from
test/SemaTemplate/instantiate-self.cpp from the clang 10.0.0 test suite:
namespace test6 {
template<typename T> constexpr T f(T);
template<typename T> constexpr T g(T t) {
typedef int arr[f(T())];
return t;
}
template<typename T> constexpr T f(T t) {
typedef int arr[g(T())];
return t;
}
int n = f(0);
}
% g++-11.0.0 -c novdqht4.cpp
novdqht4.cpp: In function 'constexpr T test6::f(T) [with T = int]':
