version 9.14.2 core dump

MAYER Hans-2

Dear All,

My environment:
Solaris 11.4 on Sparc
gcc version 5.5.0 (GCC)
bind 9.14.2
./configure  '--enable-shared' '--enable-static' '--enable-ipv6' '--without-libjson' '--with-gssapi=/usr/bin/krb5-config'


I tried to use bind 9.14.2
So far everything is working fine except I try to query this name server over the loopback interface. And this is independent if it is ::1 or 127.0.0.1
If I do such a query "dig" hangs.  At the same moment named generates a core file. Below adb traceback and pstack.
Doing the same query through the "normal" interface over the network with IPv6 or IPv4 everything works fine.
Not sure how I could fix this issue. So I stepped back to version BIND 9.11.7 (Extended Support Version) <id:084ef47>
Because this doesn't have this issue.
Any ideas how to solve ?

There's a bug in GCC on Solaris wrt thread-local storage -
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90912

As a fix for now I'd suggest using Solaris Studio C compiler.

Alternatively, you can comment out whole block in configure.ac after “Check for thread local storage” comment, run `autoreconf -fi` and BIND will now use locking, which is suboptimal, but it should suffice as a workaround.

In reply to this post by MAYER Hans-2
Hi Mayer (and other Solaris users),

could you please try following patch:

https://gitlab.isc.org/isc-projects/bind9/merge_requests/2053.patch

on your Solaris boxes with both GCC and Solaris compiler whether it correctly complains about non-GNU ld in GCC case?

Thanks,
Ondrej

RE: version 9.14.2 core dump

MAYER Hans-2

Dear All,

Many thanks for your reply.

> ... could you please try following patch ...

Yes, I will do. But unfortunately not now. Probably next week.
Does this patch also apply to 9.14.3 ?
Thanks for your great support.

Subject: Re: version 9.14.2 core dump

Hi Mayer (and other Solaris users),

could you please try following patch:

https://gitlab.isc.org/isc-projects/bind9/merge_requests/2053.patch

on your Solaris boxes with both GCC and Solaris compiler whether it correctly complains about non-GNU ld in GCC case?

Thanks,
Ondrej
