[Bug 806] New: HAVE_IPV6=YES causes SIGSEGV during delivery

Summary: HAVE_IPV6=YES causes SIGSEGV during delivery
Product: Exim
Version: 4.69
Platform: x86
OS/Version: Solaris
Status: NEW
Severity: bug
Priority: high
Component: Routing
AssignedTo: nigel[at]exim.org
ReportedBy: river[at]loreley.flyingparchment.org.uk
CC: exim-dev[at]exim.org


When HAVE_IPV6 is defined, Exim will crash (segmentation fault) during
delivery, i.e. after 'RCPT TO', or 'exim -bt':

root[at]mail:~# exim -bt root
Segmentation Fault (core dumped)
root[at]mail:~# exim -bt river
river[at]mail.toolserver.org is undeliverable: Unknown user

In the second case, the mail is unroutable, so there's no crash. Without
HAVE_IPV6 defined, everything works fine:

root[at]mail:~# exim -bt root
root[at]toolserver.org
<-- root[at]mail.toolserver.org
router = toolserverorg, transport = remote_smtp
host hemlock.toolserver.org [91.198.174.194]

I have several core dumps from this issue, and I can reproduce it, but I wasn't
able to get a stack trace from the core (I suppose Exim needs to be built with
debug symbols).

Using Exim 4.69 on Solaris 10, compiled with Sun C 5.9 124868-08.
