Internal compiler error when building rust-sdl2, FulfillmentError #43947
Description
When attempting to build orbtk, building of it's dependency, sdl2, failed with an internal compiler error.
I tried this code: https://github.com/ca1ek/orbtk/blob/master/examples/list.rs
I expected to see this happen: The program being built and ran.
Instead, this happened: An internal compiler error.
