[gentoo-amd64] How can I capture enough debug info to make a good bug report?

[gentoo-amd64] How can I capture enough debug info to make a good bug report?

[Mark Knecht]

Hi,
   On a subscriber web site I am seeing a consistent problem with both
Firefox & Firefox-bin. When I click a specific link the browser
crashes with a seg fault:

mark@lightning ~ $ firefox-bin
No running windows found
/usr/libexec/mozilla-launcher: line 119:  6108 Segmentation fault
$(type -P aoss) "$mozbin" "$@"
firefox-bin exited with non-zero status (139)
mark@lightning ~ $ firefox
No running windows found
Removing /home/mark/.mozilla/firefox/ipm4osof.default/compreg.dat
leftover from older firefox
/usr/libexec/mozilla-launcher: line 119:  6149 Segmentation fault
$(type -P aoss) "$mozbin" "$@"
firefox-bin exited with non-zero status (139)
mark@lightning ~ $

   Note that I see Firefox crashing on my Windows Vista box also, but
Internet Explorer does not, so this doesn't seem to me to be a Linux
issue specifically.

   How can I get enough info to pass along to someone and have it be useful?

Thanks,
Mark

first try the w3c validator to see if there is a problem with the web page.
it happes a lot that pages don't display correctly in firefox and sometimes
they even crash it because of some script errors and features that are
available only in internet exploder. so first search a validator in the w3c
page and try using it on the page that gives you problems. you should see
with it if there are problems.
and for what i know firefox has a reporting feature which sends the bug
reports automatically after crashes. i don't really know ho it activates
though.

1) Remerge firefox with the debug use flag
2) rebuild your kernel (if needed) with CONFIG_ELF_CORE=y
3) reboot
4) connect your page

The segfault should produce a core file that you could send to firefox devs.

If I forgot something, guys, please correct me.

You can also look at this guide:

Cool, yet another very valuable work from diego !

I was wondering why I wasn't getting core files on my gentoo when I
found the "ulimit -c unlimited" command in this guide.

Now in my bookmarks !

Are you speaking of this site?

http://validator.w3.org/

If so it doesn't even like the front page at this URL. That said the
front page doesn't crash.

http://www.investors.com/

It also doesn't like the page that is crashing. (The CANslim Select
link on the left hand side.) I don't think that URL would do anyone
here any good since you need a password to even try and get to it.

Thanks,
Mark

Will this work? I'm on a 64-bit machine. These web sites all require
flash and Java. For the most part I still feel like flash and Java
just don't work correctly on 64-bit, and maybe not even on 32-bit.

Anyway, there is no debug flag on filefox-bin which I think is 32-bit
and is crashing. I'm willing to rebuild if necessary but I think I
want to try and get some more info first.

Thanks!

Cheers,
Mark

now, on my amd64 firefox-2.0.0.6 (not bin) the pages work fine, no crashes.
in the source of the page that crashes i cannot see anything that could
break the program. the site needs to have enabled javascript, and maybe
java, but that's a little difficult to install. i have installed the
emul-linux-x86-java package with x nsplugin and als flags enabled, then
installed the flashplayer and the nspluginwrapper ad indicated here
http://gentoo-wiki.com/HOWTO_AMD64#nspluginwrapper and that worked for me.
don't count the part on java in the link indicated but only the part of
nspluginwrapper.
mine firefox flags are if you need them:
Use flags:         (-bindist) (-debug) (filepicker) (-gnome) (ipv6) (java)
(-linguas_af) (-linguas_ar) (-linguas_be) (-linguas_bg) (-linguas_ca)
(-linguas_cs) (-linguas_da) (-linguas_de) (-linguas_el) (linguas_en_GB)
(-linguas_es) (-linguas_es_AR) (-linguas_es_ES) (-linguas_eu) (-linguas_fi)
(-linguas_fr) (-linguas_fy) (-linguas_fy_NL) (-linguas_ga) (-linguas_ga_IE)
(-linguas_gu) (-linguas_gu_IN) (-linguas_he) (-linguas_hu) (linguas_it)
(-linguas_ja) (-linguas_ka) (-linguas_ko) (-linguas_ku) (-linguas_lt)
(-linguas_mk) (-linguas_mn) (-linguas_nb) (-linguas_nb_NO) (-linguas_nl)
(-linguas_nn) (-linguas_nn_NO) (-linguas_pa) (-linguas_pa_IN) (-linguas_pl)
(-linguas_pt) (-linguas_pt_BR) (-linguas_pt_PT) (-linguas_ro) (-linguas_ru)
(-linguas_sk) (-linguas_sl) (-linguas_sv) (-linguas_sv_SE) (-linguas_tr)
(-linguas_zh) (-linguas_zh_CN) (-linguas_zh_TW) (-mozdevelop) (-moznopango)
(-restrict-javascript) (xforms) (xinerama) (xprint)

again, use the stable version which is the 2.0.0.6.
by the way, the same problem on windows suggests me that you have some
settings problem inside firefox. try setting the enable javascript and only
the change status bar and disable or replace scripts. maybe you have enabled
some other type of scripts that make firefox crash.
