Re: [Devel] cvs coredump

Tue, 27 Jun 2006 10:54:39 -0700 

Hi Ray,
I played with the trusted function but I was not able to get the crash you mentioned. Is there a deterministic way to reproduce it? Could you provide me with table content and message that trigger the crash do you do any reload ?...or what is the context leading to the crash? 

do you use other modules than the ones from CVS?

Regards,
Bogdan

Hi Bogdan,


using lastest CVS today, invite message coredump seems to go away.  
but I have another core dump when using sipura 2000 to register.

Hi Ray,


it looks like a different story. Anyhow, can you print the content of 
the "np" pointer variable (p *np)....


it this something you can reproduce ?

thanks and regards,
bogdan

Dear all


I have encountered coredump with yesterday's CVS, Looks like it's 
the same issue discussed in SER forum 
http://lists.iptel.org/pipermail/serdev/2004-November/003312.html, 
please advise.


thanks

Ray
