How do I get the backtrace that you need? All I get from gdb is this:

#1 0xbffb26e0 in ?? ()
#2 0x00b56cee in ?? ()
#3 0x00000000 in ?? ()

Hello George,
if loose_route returns true, the $du should be set. Can you
send me a sample of such ACK along with the backtrace?
Cheers,
Daniel

Hi Daniel,
Thank you for looking into this. I got from SVN the patch for rev.
2420 and I applied it to my 1.2 branch. OpenSER still
crashes at the
same point. Did I get the right patch? The one I
have
changes one line
on route.c and transformations.c. I will add it
at the end
of the email.
Best regards
George
