There are:

• 32 total failures in the last 7 days: https://treeherder.mozilla.org/intermittent-failures.html#/bugdetails?startday=2020-03-15&endday=2020-03-22&tree=trunk&bug=1609074

Failure rate is about 50/50 between linux1804-64 debug and opt builds. Most of the failures seem to happen on test_popup_attribute.xhtml but not only. Test failure breakdown would be:

• test_popup_attribute.xhtml - 22 times
• browser_bug424101.js
• browser_trackingUI_report_breakage.js
• test_panel.xhtml
• browser_contentContextMenu.js
• browser_save_link-perwindowpb.js

[Hsin-Yi Tsai (she/her) [:hsinyi]]

Per comment 15, the failure rate went up in the past week. Can you please take a look and suggest the next step for this bug, Andrew? Thanks.

Comment 17

[Andrew McCreight [:mccr8]]

Some of the issue is that libc.so is a very generic signature, and lots of random stuff is getting bucketed in here. The bug as filed talks about debug, but more than half of the crashes are opt. Still, there's clearly something going wrong with test_popup_button.xhtml if not other things. I'll put the test name in the summary.

Karl, could you take a look? These are all pretty deep stacks with a bunch of libc.so and libX11.so in them. test_popup_button.xhtml is the most common failure, maybe because it opens a new window or something.

Comment 18

[Gian-Carlo Pascutto [:gcp]]

The last recognizable thing on the stack is firefox-bin!arena_t::DallocSmall. That doesn't look like it would call libc outside of a single memset that tries to poison the memory area. So memory might be quite hosed.

The thing on top of the stack is this destructor: libxul.so!nsCOMPtr<nsIPowerManagerService>::~nsCOMPtr().

This kinda reeks of a memory safety/lifetime error.

Comment 28

[Edwin Takahashi (:egao | infrequent contributor)]

I don't know how to fix this issue. As I have been discussing in Bug 1607713 with :stransky, this problem is not something I am familiar with.

The test cannot be disabled either because this is a crash that's occurring across various test suites - it just happens so that these crashes all have the same signature. Disabling each test that causes this crash would result in unacceptable loss of coverage on Linux.
