Bug#945920: Random Chromium crashes

[Jaap Joris Vens]

Hi all,

The status so far is that we have a patch that solves the problem by
re-enabling [tracing][1], but the reason that tracing was disabled in the
first place is because it depends on minified javascript. You can recompile
chromium yourself but this is not a permanent solution.

It seems that nobody has started the effort of trying to write a new patch
that removes the tracing functionality from the upstream source code, or to
find the bug and fix the way it's removed now.

Dear maintainer, could you please chime in and let us know how we could
help?

Greetings,
JJ

Dear package maintainer(s),

In case it is useful information, this issue affects me as well, and
has for several weeks.  Chromium is usable for only a few minutes
before it crashes with a backtrace almost identical to those already
shared.  It does not seem to matter how many or what kind of pages are
open, or whether the browser is actively being used / receiving window
manager focus or not.

Please let me know if there is anything I can do to help identify the
problem or test a fix.

Bug#945920: Random Chromium crashes

[Jaap Joris Vens]

Hi all,

I have tried building chromium after applying
[tracing.patch](https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=945920;filename=enable-tracing.patch;msg=14)

Unfortunately, it failed early in the build process with the following
error:

ERROR Unresolved dependencies.
//third_party/perfetto/gn:zlib(//build/toolchain/linux/unbundle:default)
  needs //third_party/zlib:zlib_config(//build/toolchain/linux/unbundle:default)

Hi Eloston,

Thanks for figuring out the cause of these random crashes! However, I was
unable to recompile chromium from source following your instructions. I got
the following error message at step 4b:

Hi,

yes, you are right, my patch only fixes the task manager crash.

I now took a look at all backtraces, and all apart the first one
(probably older version?) seem to be the same "other" instance:

I am not quite following the intricacies of this crash anymore, but might
this be something that we will need to report upstream?

Bug#945920: Chromium randomly crashes in the latest version.

[Jaap Joris Vens]

I have attached the output of `chromium --debug` after reading the
instructions in /usr/share/doc/chromium/README.Debian and installing the
chromium-dbgsym package. This always crashes on startup, not randomly, so
I probably did something wrong.

Any help would be appreciated.

Gr,
JJ

Bug#763633: apt-file: Segmentation fault

[Jaap Joris Vens]

I found the problem: There is an error in my Perl installation. After 
upgrading I didn't replace the Perl interpreter used by local::lib. I 
solved the problem by manually removing the directory $HOME/perl5


Sorry for bugging you dear maintainers with a problem unrelated to 
apt-file. This bug can be closed.
