In the 1st case it fails in ast_copy_string. Is it reproducible if built dont-optimize?

In the 2nd case it fails in libiksemel. What library version are you using?

this is when juliedube01@gmail.com is offline, it crashes each time.

debug info is in offline.txt

casper: for your questions:
1st crash is really hard to reproduce.

im using the debian package (sarge, stable).

polux:/tmp# dpkg --list|grep libik
ii  libiksemel1    1.2-1          iksemel is a C library for the Jabber IM pla
ii  libiksemel1-de 1.2-1          iksemel is a C library for the Jabber IM pla

Another crash with this exact scenario: just place an invalid recipient when sending a message.

junky: are your backtraces from dont-optimize'd build?
By: Andrey S Pankov (casper) 2006-06-22 10:58:48

Could you please print insert->id, pak->id, sizeof(insert->message) in GDB?
By: Clod Patry (junky) 2006-06-27 22:32:59

So far, that patch fixed all my 2 issues:
- dest user is offline
- dest user email is invalid.

It was just a bad 3rd argument passed to ast_copy_string and pak->id is NULL sometime.

Let me know whatcha think.

It seems like that bug was already fixed in another way in the trunk r36175...
By: Clod Patry (junky) 2006-06-30 11:04:37

i can confirm Revision: 36176 fixed these problems.
