Hi Jonathan,

this seems not related to carrierroute, as you can see from the backtrace the 
crash is in the parser code. Would be interesting if this is related to some 
invalid message, or an unrelated error. Have you tried to replay the message 
in your lab that causes the crash, after isolating it from the backtrace?
You should also take a look into the "tp" pointer with the debugger, try to 
investigate why it has an apparently invalid value here.

Cheers,

Henning
