Hello,
in gdb, please do:
frame 1 print lstr
and send me the output. Strange that in frame 0, the stack seems to be corrupted.
Thanks, Daniel

How do I get the backtrace that you need? All I get from
gdb is this:
#0 0x080844a7 in ?? () #1 0xbffb26e0 in ?? () #2 0x00b56cee in ?? () #3 0x00000000 in ?? ()
Check if you got a core file, and then: gdb /path/to/openser /path/to/core_file
# bt
Cheers, Daniel
Best regards
George

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
