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".

M_New_Doc_Ureg::sendAnswer code:

unsigned char * send_buf = new unsigned char[sgds_name.size()];
send_buf = (unsigned char *)sgds_name.c_str();
AMessageInfo ami;
ami.SetFromClient(crypto_name);
ami.SetFromApplication(crypto_app);
ami.SetFromSession(crypto_inst);
ami.SetMsgCrypto("none");
ami.SetDocType("CRYPTO_REVOKECERT");
ami.SetDocVersion("1");
ami.SetDocId(currreferens);
ami.SetMsgSysSource("SGDS_3");
Log::message("Sending Message", DEBUG_LOG);
Log::message("DocType"+ami.GetDocType(), DEBUG_LOG);
CustomServer::instance()->send_message(send_buf, sgds_name.size(), ami);
if(send_buf != NULL) delete send_buf;
Log::message("Message Sent", DEBUG_LOG);

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?
