800 crashes on release makes this a top 40 to 50 crash.

Comment 2

[Benjamin Smedberg]

Crash is here: http://hg.mozilla.org/releases/mozilla-aurora/annotate/56f456359253/xpcom/components/nsComponentManager.cpp#l475 at address 0xc0010 and called from http://hg.mozilla.org/releases/mozilla-aurora/annotate/56f456359253/xpcom/components/nsComponentManager.cpp#l388

That makes me think that something is wrong with our library loading/linkage setup.

[Mike Hommey [:glandium]]

Is it all on android, and all on >= 35?

Comment 4

[Kevin Brosnan [Ex-Mozilla]]

It is platform independent and is not new crashes dating back to fx 13, https://crash-stats.mozilla.com/report/list?signature=nsComponentManagerImpl%3A%3ARegisterModule(mozilla%3A%3AModule+const*%2C+mozilla%3A%3AFileLocation*)&range_value=7&range_unit=days

Comment 5

[Mike Hommey [:glandium]]

Happening more on Linux than other platforms, though

Comment 6

[Kevin Brosnan [Ex-Mozilla]]

Linux includes Android in this view.

Comment 7

[Mike Hommey [:glandium]]

I picked another crash and looked at it:
https://crash-stats.mozilla.com/report/index/7fac8278-aaf5-476f-a866-58ab52141128

I see nothing in the assembly or the libxul.so contents that could explain this behavior. A raw dump might be useful here, although it may require a full dump, but I can't tell without looking. Requesting access in bug 1109998.

Comment 8

[Mike Hommey [:glandium]]

Unfortunately, the raw mini dump is not sufficient to tell anything. I'd need a full dump. Can breakpad actually create full dumps on Android? If yes, how can we get such dumps from crashing users?

Comment 9

[(not currently active) Ted Mielczarek]

Breakpad does not have that functionality, sorry.

[Calixte Denizet (:calixte)]

There are still some crashes so reopen it.

Comment 14

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

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.
