1608746 - Fission crash in [@ NS_GetSanitizedURIStringFromURI]

Status: RESOLVED DUPLICATE of bug 1574017

(Core :: DOM: Navigation, defect, P1)

Description

[Chris Peterson [:cpeterson]]

This bug is for crash report bp-4778a50e-1759-4713-bfec-a7bd20200113.

I hit this crash every time I load following URL when I have Fission enabled:

https://onedrive.live.com/about/en-us/plans/

This is not a recent regression. I can reproduce at least as far back as 70 Nightly with Fission enabled.

Wasn't Anny looking into some PostMessage issues, perhaps this is related?

@ bhackett, I bisected this crash with mozregression. I think this crash is a regression from your postMessage bug 1124122 (fixed in Firefox 69):

https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=19f38c9cdd671aac3fc57ccde19560f337d7d992&tochange=51440617724b12fec25ba05b0b2e25241c92683e

Bug 1124122 is a DevTools bug that appears to be unrelated to Fission. Could this NS_GetSanitizedURIStringFromURI crash affect non-Fission users? I was only able to reproduce this bug with Fission enabled.

I can reproduce on both macOS and Windows.

I was able to reproduce this when I have an existing "https://onedrive.live.com/about/en-us/plans/" already opened in one tab and I open the URL for the second time. I tested this with my fix from bug 1574017 and I didn't see the crash anymore.
