Description: 
hello!

I have problem at least with asterisk 1.6.1.[2,4] and t.38 on x64
platform.
Asterisk segmentation fault after full proxy call to my customer who tries
send / receive fax (t.38).

    -- Called 7499XXXXXXX at 7499XXXXXXX
    -- SIP/7499XXXXXXX-0996bd98 is ringing
    -- SIP/7499XXXXXXX-0996bd98 answered SIP/YYYYYYY-SIP-b00dcb08
    -- Packet2Packet bridging SIP/YYYYYYY-SIP-b00dcb08 and
SIP/7499XXXXXXX-0996bd98

---------------------------------------------------------------------- 
This is incoming call to customer with t38pt_udptl set to 'no' for his
peer.

Short scheme:
PSTN --> E1 ISDN PRI --> cisco as5400xm --> SIP-t38pt_udptl=yes -->
asterisk-1.6.1.4_x64 --> SIP-t38pt_udptl=no -->
asterisk-1.6.1.4_x86(customer)

As described in Description section above and that scheme:
SIP/YYYYYYY = t38pt_udptl=yes = cisco as5400xm
SIP/7499XXXXXXX = t38pt_udptl=no = asterisk-1.6.1.4_x86(customer)

Hope this helps.
