Additional Information

Just click "Load iframe" in the Fiddle and Electron will crash, I tested this on windows as well with the same result.

This appears to be a problem from at least v14. Also Windows fails with Electron exited with code 2147483651.

I'm fairly certain this is a duplicate of #28407. Using registerStringProtocol here also causes a crash. Changing the gist here to load index.html via my-app:// doesn't crash.

Closing as a duplicate, please ping me if you think this is incorrect.

@dsanders11 :

I'm still finding (in Electron 21.2.0) that loading a PDF in an iFrame fails to display the PDF, and loading a PDF in a webview crashes Electron.

Here's an Electron Fiddle gist that demonstrates this:

Could you please take another look?
