[OpenSER-Users] segfault with general protection error

[Marcello Lupo]

Hi to all,
today i got a segfault with general protection error openser 1.2.2  
notls under

Linux 2.6.16.27-0.9-smp #1 SMP Tue Feb 13 09:35:18 UTC 2007 x86_64  
x86_64 x86_64 GNU/Linux.

It is due to:

May  8 18:29:25 voip /data/openser/sbin/openser[19569]: val2str:  
Destination buffer too short
May  8 18:29:25 voip /data/openser/sbin/openser[19569]: print_values:  
Error while converting value to string
May  8 18:29:25 voip /data/openser/sbin/openser[19569]:  
ERROR:acc:acc_db_request: Error while inserting to database
May  8 18:29:26 voip /data/openser/sbin/openser[19560]: child process  
19573 exited by a signal 11
May  8 18:29:27 voip /data/openser/sbin/openser[19560]: core was  
generated

I examined the core dump and it has been caused from the same thing  
that happened to me on October 2007 on another installation.
I already posted the question to the list without getting any response.

http://lists.openser.org/pipermail/users/2007-October/013796.html

I post now the new gdb trace.

I'm a very beginner using gdb but like very much to know why this is  
happening.

Core was generated by `/data/openser/sbin/openser'.
Program terminated with signal 11, Segmentation fault.
