Since upgrading to glibc 2.14.1 (from 2.13-r4) I see frequent crashes in firefox. The following is recorded in .xsession-errors: firefox: res_query.c:251: __libc_res_nquery: Assertion `hp != hp2' failed.
I cannot confirm this bug. Perhaps you could do the following: (a) Provide more information about your system and Firefox versions (emerge --info is a must). (b) Have you tried rebuilding Firefox and/or its dependencies (i.e., nss, nspr) ? Thanks.

I tried rebuilding nss, nspr and firefox (and rebooting). Still get the crash - which by the way I had never experienced before. Apologies for not providing emerge info before, it's attached now.
Thanks for that. The very same bug seems to be spotted at Arch Linux (https://bugs.archlinux.org/task/24615).
1) Please post the output of `emerge -vpq www-client/firefox' in a comment. 2) At which point during firefox's run time does it crash? Starting up, loading some page? Can you obtain a GDB backtrace?

I don't have gdb installed at the moment, give me just a while.

http://sourceware.org/bugzilla/show_bug.cgi?id=13013
I can confirm that the patch linked to in comment 7 corrects this issue.
Can we get the patch in portage, please? Firefox is unusable as of now.
(In reply to comment #9) > Can we get the patch in portage, please? Firefox is unusable as of now. Hi, For temporary fix i thinks you must use this : mkdir -p /etc/portage/patches/sys-libs/glibc-2.14.1 cd /etc/portage/patches/sys-libs/glibc-2.14.1 wget "http://sourceware.org/bugzilla/attachment.cgi?id=5855" -O fix_assertion_hp2_failed_glibc.patch
And re emerge glibc.
Thank you 2 times. One for the patch works perfectly, a second for introducing me to use the user patch system in portage.
gentoo, please apply this to portage. this bug has been resolved against glibc since july
This issue has nothing to do with Firefox, but only glibc. I encounter the problem with e.g. subtle or git. The patch given by lamusic seems to fix it.
I have the exact same problem. Trying the patch right now. Would be nice if I could just downgrade glibc, but portage refuses.
this is in glibc-2.14.1-r1 http://sources.gentoo.org/gentoo/src/patchsets/glibc/2.14.1/0052_all_glibc-2.14-resolv-hp-assert.patch?rev=1.1
