A nearly identical crash in _nss_dns_gethostbyname2_r is tracked in bug 329974. I suspect it's coming from the same bug.

This seems to be affecting i386 only.
Opening a samba task since the crash is probably libsmbclient-related.

To anyone that can reproduce this bug on a Jaunty test system:
Could you test and install glibc 2.9-4ubuntu6.1~ppa1 from my PPA at https://launchpad.net/~ttx/+archive/ppa and let me know if it fixes the problem or not. You should upgrade the libc6 binary package (which should pull the libc6-i686 or libc6-amd64 and libc6-dev packages). Please reboot before testing to make sure you fully test the right glibc.

It looks like a conflict between avahi and samba. According to this blog post, its apparently fixed in avahi:

Chuck: I fear it's more general than that. There is a trends towards _nss_*_gethostbyname_r crashes on jaunty/karmic. Failing to reproduce, I can't confirm but it might stem from bug 374674.

[Till Kamppeter (till-kamppeter)]

I move it to glibc, but I do not mark it as duplicate, as there is no way to automaticaly pass over all the duplicates of this bug.

[Thierry Carrez (ttx)]

glibc was updated in karmic removing the problematic patch. Would be good to confirm that the problem is gone on karmic now.

[Thierry Carrez (ttx)]

This is believed to be fixed in karmic by bug 374674 fix. Please reopen if you can reproduce this on a current karmic setup.

[Thierry Carrez (ttx)]

Not a samba bug.
