Very large error file creation on exponentially growing type

[oli-obk]

I tried this code:

struct B<T: 'static>(&'static B<(T, T)>, T);

static BOO: B<u32> = todo!();

I expected to see this happen: compilation error

Instead, this happened: disk space filled up with a large error file (it terminates at some point, just probably not this year).
