<pre>Won't compile on clang++ (works in gcc, msvcc, icc)
template<typename... CA>
void foo(CA... y, int x) {
x++;
}
int main(int argc, char **argv) {
void(*bar)(float, int) = &(foo<float>);
bar(1.4f, 1);
}
Will compile on all compilers:
template<typename... CA>
void foo(int x, CA... y) {
x++;
}
int main(int argc, char **argv) {
void(*bar)(int, float) = &(foo<float>);
bar(1, 1.4f);
}
The only difference here being the order of arguments in foo(). I also tested
this against all the versions of clang++ on <a href="https://godbolt.org/">https://godbolt.org/</a> and found it
was broken on all versions up to trunk.</pre>
