910822 - [SOLUTION] Can't test 1.5 years of old Nightly builds on Debian jessie/sid: linux-x86_64 2011-01…2012-06 crash on startup

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[[:Aleksej]]

This is not a Firefox bug, and probably cannot be fixed by doing anything to Firefox, but it hinders regression window search.


On Debian jessie/sid, Firefox linux-x86_64 nightlies between 24 Jan 2011 and 19 Jun 2012 crash on start-up after the profile manager:

wfm 2011-01-24-03-mozilla-central-firefox-4.0b10pre.en-US.linux-x86_64
crash 2011-01-25-03-mozilla-central-firefox-4.0b10pre.en-US.linux-x86_64
…
crash 2012-06-18-03-05-31-mozilla-central-firefox-16.0a1.en-US.linux-x86_64
wfm 2012-06-19-03-05-38-mozilla-central-firefox-16.0a1.en-US.linux-x86_64

The stack traces are not good: 1884f6f7-9bec-470f-9aa8-ab5812130829.



32-bit builds do not work, either (apparently due to a known problem in Debian, see below):

$ ./firefox
XPCOMGlueLoad error for file /opt/fx/2012-03-10-03-10-46-mozilla-central-firefox-13.0a1.en-US.linux-i686/libxpcom.so:
libxul.so: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

Apparently that's bug 704298 and/or bug 723487.  I see I don't have ia32-libs and ia32-libs-gtk installed, but installing them is currently impossible due to libjack0 and libopus0: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=674467

Neither of these seem to be Firefox bugs nor are they something we can support. This all has to do with the libraries Debian is providing. You'll have to report this to Debian but it'll be up to them to decide if they want to support old unsupported Firefox versions.

Yes it hinders regression window finding but that's the nature of the beast.

With the GDB backtrace below, I've found through bug 497251 that removing libfreebl3.so fixes the problem.  When libfreebl3.so is present, the first start (profile creation?) fails.  It's a part of NSS, and according to that bug, Firefox may be trying to use some libraries from the system NSS.

(removing the system libfreebl3.so instead doesn't work)

Apparently renaming the library breaks Firefox networking.

Comment 4

[[:Aleksej]]

Actual solution found: overwrite the build's libfreebl3.so with the Debian's one from /usr/lib/x86_64-linux-gnu/nss/libfreebl3.so

mv libfreebl3.so libfreebl3.so.bak && cp /usr/lib/x86_64-linux-gnu/nss/libfreebl3.so libfreebl3.so
