Internal compiler error in MSVC 2017 15.5
This is a regression compared to 15.4 and it prevents the Fruit library:
https://github.com/google/fruit
from working with MSVC 2017 (while it worked with MSVC 2017 15.4).
A minimal sample code that reproduces the issue is attached.
Compiling that produces this error:

Code to reproduce the issue:
struct Zero {
static constexpr const int value = 0;
};
template <typename... Ts> void consume(Ts... ts);
int transform(int n);
template <typename... Indexes> void f() {
consume(transform(Indexes::value)...);
}
void g() {
f<Zero>();
}
Thank you for your feedback! We have fixed the problem in an upcoming release. Thank you for helping us build a better Visual Studio!
