[reSIProcate] TransactionState::process crash

[palladin]

Dear resip devels,
resiprocate-1.8.8
please consider next issue:
TransactionState.cxx:624 - if(sip->const_header(h_To).param(p_tag) != 
to.param(p_tag))

In my custom case To header was malformed: 
To:<sip:bbbzzz>bbbzzz.com>;tag=145501840
and const_header generated unhandled exception, which caused application 
crash.
Should you out any try/catch there?

Sincerely,
tez.
