Hello. I have some trouble. Soft work under HP-UX 11.11, compiled by aCC. Soft worked correctly. Now soft always create core file and it's state "killed by 10".

Data from core file:

M_New_Doc_Ureg::sendAnswer code:

I need help.

This indicates heap corruption. You need to download the latest gdb and enable heap checking:
(gdb) set heap-check on string on
http://www.hp.com/go/wdb

unsigned char *send_buf = new unsigned char[sgds_name.size()];

Do you need to use sgds_name.size() + 1?
It appears send_message doesn't range check properly?
