asterisk users - Nov 2003 - * is crashing, when the call is accepted (H.323 -> SIP)

I'v got the following scenario: Two clients (ohphone) are calling (one
at a time) the host with asterisk, which then connects to the SIP
client.

One of these hosts let's asterisk crash with a segmentation fault (i can
provide the core file, if needed) in the second, the SIP client accepts
the call. However .. if that client get's to the voicemail instead,
because the SIP client is offline, asterisk will not crash.

I do have a coredump from *, if that is needed.

Client (crashing *):
Slackware
libc6 2.3.2
PWLib 1.5.2
OpenH323 1.12.2
OhPhone 1.4.1  

Client (not crashing *):
Debian Sid
libc6 2.3.2.ds1-10
PwLib 1.5.2 (libpt-1.5.2)
OpenH323 1.12.2 (libopenh323-1.12.2)
OhPhone 1.4.1-1

* Host:
Debian sarge/sid mix
libc6 2.3.2.ds1-8   
PwLib 1.5.2 (libpt-1.5.2-2)
OpenH323 1.12.2 (libopenh323-1.12.2-3)
asterisk 0.5.0-2
asterisk-oh323-0.5.6

Client receiving the call:

Any suggestions how this can be prevented ?
What additional info is needed ?
