• [X] Bug Report

• [ ] Feature Request

• [X] Successfully reproduced against the latest version of NW.js?

Current/Missing Behavior

NW.js segfaults immediately upon running chrome.privacy.services.autofillEnabled.set. Other chrome.privacy settings do not cause this.

Expected/Proposed Behavior

Doesn't kill itself.

Additional Info

• Operating System: Kubuntu 22.04
• NW.js Version: 0.89.0
• Code snippet:

package.json:

{
"name": "segfault",
"main": "main.js"
}

main.js that segfaults:

chrome.privacy.services.passwordSavingEnabled.set({value: false});
chrome.privacy.services.autofillEnabled.set({value: false});
chrome.privacy.services.spellingServiceEnabled.set({value: false});

main.js that doesn't segfault:

chrome.privacy.services.passwordSavingEnabled.set({value: false});
// chrome.privacy.services.autofillEnabled.set({value: false});
chrome.privacy.services.spellingServiceEnabled.set({value: false});

Note that the path of libnw.so is due to NW.js being installed from a .deb package I maintain, which just packages binary releases from nwjs.io and installs them in /usr/lib/nw.js/.

@skylarmt Do you have libatomic installed?

[skylarmt]

@skylarmt Do you have libatomic installed?

Yes, at least on my dev machine, which had the same crash but with a less helpful stacktrace (unlike the VM, I think it's missing a utility that helps make useful bug report stack traces).

~$ sudo apt install libatomic1
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
libatomic1 is already the newest version (12.3.0-1ubuntu1~22.04).
libatomic1 set to manually installed.

Looks like it was missing from the VM though, and installing it there maybe helps?

[skylarmt]

Another thing to note is this only seems to occur when an app hasn't successfully launched before. Deleting its data folder in ~/.config causes the bug again. I recall running into this crash on a laptop a few months ago, but assumed the laptop was just old and had some incompatibility, so I downgraded NW.js by a year or two and whatever version that was didn't crash.

Note that autofillEnabled is marked as deprecated in the types: "since Chrome 70. Please use privacy.services.autofillAddressEnabled and privacy.services.autofillCreditCardEnabled."

[skylarmt]

It shouldn't segfault though.

@skylarmt After installing libatomic1 in the VM, does it still segfault? It doesn't for me.
