Gnokii smsd SIGSEGV

[Federico Sevilla III]

Hi everyone,

I'm using Gnokii smsd from the 0.4.3 release, which is running on a
Debian GNU/Linux system (I am testing -smsd packages I'm building for
submission to the main package maintainer). I built both pq and mysql
modules, but am only using the pq module, and am connecting to a
PostgreSQL server that is on another machine in the LAN. The unit is a
Nokia 3210.

I've noticed that thrice already so far, smsd would segfault after
awhile. "Awhile" being a few days, with seemingly nothing peculiar
happening (eg: no active inbound or outbound messages or calls). During
the third session I ran smsd through strace, generating a full log of
system calls.

A bzip2-compressed log is available (273KB compressed, 74MB extracted)
online at <http://jijo.free.net.ph/smsd.strace.log.bz2>.

The last 50 lines of this log are:

smsd is running again, albeit not being logged by strace anymore. It
normally runs -- and works really well -- for a few days or even a week
or so before crashing. I hope the information in the strace will be
useful. Please let me know if you need any more information or if this
has been fixed in CVS.

Cheers! :)
