Description
I tried this code:
I found this code would make rustc eat more than 20 gb of memory until OOM killer stopped it
fn T<T>(x: &T::<T::<T::<T::<T::<T::<T::<x, HT::U<T::<T::<x, T::<T::<T::<T::<T::<T::<T::<T::<x, T::<T, T>>T::<x, HT::U<T::<T::<x, T::<T::<TT::<T::(<T::<T)::<x, )T>>, T>>, T::<T:T, T>>>>>, T>>, T>>>, T::<x, T::<T::<T::<>>, TI expected to see this happen: explanation
Instead, this happened: explosion
