Mike, backfills show that this is caused by the changes in Bug 1617983:
https://treeherder.mozilla.org/#/jobs?repo=autoland&group_state=expanded&resultStatus=testfailed%2Csuccess%2Crunning%2Cpending%2Crunnable&tochange=6c8c53328c214060552a084c339f411e3b5bd007&searchStr=linux%2Cccov%2Creftest&fromchange=69d466eda909a2f96ed4cf8a42ec19348cd87242&selectedJob=292440916
Could you please take a look?

The stack shows that we're crashing in a call to PHC's replace_free inside of the thread in the parent process that does async process launch...
njn, is this a problem in PHC? Or is PHC just being asked to free a nullptr?
Or, jld, is this more likely a problem in the way we're async-launching the process / forking on the Linux server?

There's a bunch of 0xe5e5e5e5e5e5e5e5 in those registers, so it smells like a use after free.

See also bug 1603574 comment #5; there seems to be a bug in the gcov runtime. I wondered if the thing we're doing that's provoking the bug might be forking on multiple threads concurrently, which is unlikely but possible, but that's just a guess. Also I notice bug 1607004 comment #0, where the crash is under dlclose rather than fork.

I think PHC's presence in the stack is a red herring. PHC wraps the allocator, but lets the vast majority of requests through to the allocator. The presence of the Allocator<MozJemallocBase>::free(void*) frame above PHC's replace_free is consistent with a free() call that is being passed through to the allocator.

Finally managed to get some linux1804-64 debug ccov builds going on try: https://treeherder.mozilla.org/#/jobs?repo=try&revision=b2a80e74ccf2296bb5847ff6a191b7a2966c03eb

Mike, the failure occurs on Linux 18.04 x64 CCov opt, which was not triggered in your try push. i added the jobs and the failure still shows up. Please check try results.

Thanks, apavel. The reason I wasn't running Linux 18.04 x64 CCov opt is because Pernosco / rr doesn't work with opt builds, and we must use debug builds. That's why my try push has debug builds.
Here's a more recent push where I think I've got the failure reproducing... I've aske Pernosco for a trace and am waiting to hear back: https://treeherder.mozilla.org/#/jobs?repo=try&revision=817bbe219fe8b845770512e66aaabae1c00882aa

Based on comment 5, I suspect what we should probably do is disable the privileged about content process on ccov builds. This is unfortunate, since we're going to be missing out on coverage measurement for more and more of the browser as we start taking advantage of the privileged about content process. I don't know how else to deal with this though. :/
I have had 0 luck getting Pernosco traces for this, which is doubly unfortunate.
marco, is it alright if I just go ahead and disable the separate privileged about content process for ccov builds?

Mike, would this be better classified under DOM::Content Processes? It looks more related to ipc than to layout to me.

It's hard to say. This is maybe a bug in our process launching code, or maybe a bug in our IPC layer, or maybe a bug in our ccov code. I really don't know. :(

Yeah, it's unfortunate but it sounds like it's the best option for now.

We should retry after we switch the coverage build to use Clang instead of GCC, maybe the bug is in ccov code and it will be fixed, or the bug is timing-dependent and it will disappear with a different compiler.
Since this is Linux-only, can we disable the privileged about content process for Linux only?

The priority flag is not set for this bug.
:dbaron, could you have a look please?
For more information, please visit auto_nag documentation.
Triaging this as a bug in gcov based on comment 5. That's not particularly high-confidence, but I'm reasonably confident that Layout is not the right place (just because the crash happened in a reftest).

Pretty sure this is the same issue we're seeing in bug 1565352, and should go away when we switch to Clang.

Because this bug's Severity has not been changed from the default since it was filed, and it's Priority is P3 (Backlog,) indicating it has been triaged, the bug's Severity is being updated to S3 (normal.)

The last report is unrelated to this bug which is Linux specific and in looking at logs it seems that there is nothing related to ccov.
:aryx, could you check why this failure has been reported here ?
