1905107 - Crash in [@ TppRaiseInvalidParameter]

Status: NEW

(External Software Affecting Firefox :: Other, defect, P3)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

In the last two weeks, we have observed an increase in crash volume for this signature. The reports I read are all about external DLL files in the stacks

• weasel.dll e.g. bp-94292f5f-d494-40ba-b94a-ea3070240626 - related to RIME input method engine https://github.com/rime/weasel
• sgephook.dll e.g. bp-9a1e3060-1fa5-4b0d-b206-ab9e70240626 - by Beijing SkyGuard Cybersecurity Technology Co., Ltd. They offer a data loss prevention provider (DLP) https://www.skyguard.com.cn/en/
• f_webff.dll e.g. bp-f89b36d3-a47b-4924-a251-602ca0240613, likely also a DLP https://en.fasoo.com/

The changes in bug 1898718 and bug 1899703 are about DLP and shutdown hangs.

Comment 2

[Greg Stoll :gstoll]

Those are for the DLP SDK, which to our knowledge no one is using yet. (also the stacks for the shutdown hangs in those cases look different)

Comment 3

[Greg Stoll :gstoll]

As of today the vast majority of these crashes over the last 7 days are from weasel.dll (69 vs. 5 with f_webff.dll and 1 with sgephook.dll). So I'm going to focus on that.

This only seems to happen with version 0.16.1 of rime and appears to match issue 1286 in their GitHub repo.

Comment 5

[Greg Stoll :gstoll]

Somehow I missed that this is a crash on startup. Looks like this can happen when we're exiting after applying updates, or when we're exiting quickly for some other reason. I have a reasonable-looking stack trace with weasel.dll symbols resolved, so I'm going to post to that thread with more information.

[BugBot [:suhaib / :marco/ :calixte]]

The bug is linked to a topcrash signature, which matches the following criterion:

• Top 10 desktop browser crashes on nightly

:gstoll, could you consider increasing the severity of this top-crash bug?
