[reSIProcate] stack crashes on windows XP

[Hagai Sela (TA)]

Hi,
My resiprocate based UA crashes on a Windows XP machine, and I think it
has something to do with sending ACK messages. This is the stack trace:

  msvcr71d.dll!_threadstartex(void * ptd=0x01c56630)  Line 241 + 0xd C
  kernel32.dll!7c80b683()  

I think it somehow has a problem creating a transaction id for the ACK
requests. Can someone give me any pointers on how to debug this?
 
Hagai.
