--- Comment #1 from IOhannes m zmölnig <dev at umlaeute dot mur.at> ---
ouch, i've actually posted my initial test-case that uses templates.
The original code looked like
```C++
template <typename T>
T test(void) {
constexpr auto one = T (1);
constexpr auto oneThird = one / (T) 3;
return oneThird;
}
int main() {
test<long double>();
return 0;
}
```
Using this instead
```C++
void test() {
constexpr auto oneThird = ((long double) 1)/ ((long double) 3);
}
```
has of course a slightly different error message, namely:
```
$ g++ -save-temps -o test.o test.cpp
test.cpp: In function 'void test()':
test.cpp:2:47: error: '(1.0e+0l / 3.0e+0l)' is not a constant expression
2 | constexpr auto oneThird = ((long double) 1)/ ((long double) 3);
|
```
(it seems like I can no longer edit my original bug-report; sorry for the
confusion)
