The [use custom session protocol spec](https://github.com/electron/electron/blob/fea165bef8e1edf99b6e1500da89d015e76cc8e1/spec/api-protocol-spec.js#L874) is curently crashing on master on Windows 64-bit.

For some reason it isn't failing the build though which is why it wasn't caught earlier, will look into that separately.

I bisected and it started happening in https://github.com/electron/electron/pull/9358
