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

Hello,
I have the following line in my script which causes OpenSER
(1.2) to
crash when the execution gets there for an ACK. if ($du=~"[@:](192.168.|10.|172.(1[6-9]|2[0-9]|3[0-1]).)") It gets at this line when an ACK is received and after
loose_route()
returns true. So I am guessing the destination uri is
null at that
point and the check causes OpenSER to crash.
If I add the following check then everything works fine. if (isdsturiset() && $du=~"[@:](192.168.|10.|172.(1[6-9]|2[0-9]|3[0-1]).)")
can you test with devel version? I applied a patch, and if
ok, I will
backport. Thanks for reporting.
Cheers, Daniel
thank you
George
