Summary:                    [patch] Libpri crashes when receiving Message Type
(100)
Description: 
Production system, with a 2 PRI card.

Installed last week, we have had two segfaults, same symptoms:

syslog:
Sep  7 11:13:13 gwensa kernel: [15316.468308] asterisk[2716]: segfault at
30 ip b7a5ed82 sp b7a4e1f0 error 4 in libpri.so.1.4[b7a50000+47000]

messages:
[Sep  7 11:13:13] ERROR[2716] chan_dahdi.c: !! Don't know how to
pre-handle message type Unknown Message Type (100)
[Sep  7 11:13:13] ERROR[2716] chan_dahdi.c: !! Don't know how to
post-handle message type Unknown Message Type (100)

After the latter messages, Asterisk crashes.

---------------------------------------------------------------------- 
The unknown message 100 is the REGISTER message.  This message is handled
in the libpri 1.4.12-beta versions to support the call completion
supplementary services.

The issue_17968_v1.4.patch is against the 1.4 branch.
The issue_17968_v1.4.11.4.patch is against libpri v1.4.11.4.

The patch files correct the double free of a call record when receiving an
unsupported/unknown message type.
