Doesn't seem to be happening on every site, http://www.newgrounds.com/portal/view/694230 seems to work - I get the activate UI.

assertion failed: unsafe { is_in_main_thread() }

But the stack is busted, because we're missing symbols for the XUL library? We have the symbols for firefox/libmozglue of this build.

I think that something is busted in this install. I checked the uploaded symbols for this build and this is the symbol file for XUL of this build: XUL/7196A3AF2E7A3A4CAB8721148C2C7FAC0/XUL.sym

But this crash is looking for 31218C86B870353DB5335912BC451C4F0, which is corrupted.

Marcia, I think it would be valuable to install this nightly fresh into another directory and then compare the XUL file: http://ftp.mozilla.org/pub/firefox/nightly/2017/06/2017-06-07-03-02-06-mozilla-central/firefox-55.0a1.en-US.mac.dmg

It's likely an update or reinstall would fix this, but it might be valuable to have the update logs from the corrupted build.

I think this is happening because I have webrender turned on, when I turned it off I couldn't reproduce it. I suspect that may be the case with the other reports as well. If they have WR! in the app notes it means they have the pref on in about:config.

That's very strange. Can you make sure to inform the webrender team about this? And if webrender is in fact corrupting crash-stats that might be worth a bug all by itself.

Per bug 1371017 comment 3, the missing symbols are because llvm-dsymutil is crashing trying to write a dSYM for libxul.

Comment 6

[Benjamin Smedberg]

Marcia, were you able to reproduce this on one of the nightlies that didn't have missing symbols?

Not yet. Wondering if the site changed. I can close this as WFM now and reopen if it is seen again.
