Illegal hardware instruction when running triangle example with recent nightly

Hi,

I'm using `rustc 1.33.0-nightly (a2b0f247b 2018-12-30)`. My graphics chipset is `Intel® HD Graphics 5500 (Broadwell GT2)`.

When running `cargo run --example triangle --features vulkan`, I get the following output (the window opens briefly before crashing with the following - I assume this isn't intended):


```
