Problem with HP-UX extended procedures that use C++ Standard library

Question

I am experiencing a problem with using the C++ standard library on HP-UX inside my extended procedures.
Here is the definition for the library and procedures:
-bash-3.2$ more nuhash2.sql
CREATE OR REPLACE LIBRARY xp_nuencryption_l
AS
'/home/jchamber/datasecure/lib/libxp_nuencryption.sl';
CREATE OR REPLACE PACKAGE xp_nuencryption
AS
PROCEDURE xp_nuhash2;
END xp_nuencryption;
CREATE OR REPLACE PACKAGE BODY xp_nuencryption
IS
PROCEDURE xp_nuhash2
IS EXTERNAL
LIBRARY xp_nuencryption_l
NAME "xp_nuhash2"
LANGUAGE C;
END xp_nuencryption;
Here is the PL/SQL test program:
-bash-3.2$ more testnuhash2.sql
SET SERVEROUTPUT ON SIZE 1000000
DECLARE
BEGIN
xp_nuencryption.xp_nuhash2 ();
END;
Here is the implementation of the extended procudure - notice how we are using the C++ Standard library:
-bash-3.2$ more xp_nuhash2.cpp
#include <string.h>
#include <iostream>
#include <fstream>
class MyException {
public:
MyException() {}
int func(std::ofstream& fout )
fout << "func: About to throw exception in func()" << std::endl;
throw MyException();
extern "C"
void xp_nuhash2 ()
std::ofstream fout("/home/jchamber/xp_nuhash2.txt");
try {
fout << "xp_nuhash2: About to call func()" << std::endl;
func(fout);
catch (MyException& ex) {
fout << "xp_nuhash2: caught MyException" << std::endl;
fout << std::flush;
fout.close();
Here is how we build the library on HP-UX:
# compile
aCC -g -AA DA2.0W DS2.0 +z -c xp_nuhash2.cpp -o xp_nuhash.o
#link using aCC
aCC -g -AA DA2.0W DS2.0 +z -b -o /home/jchamber/datasecure/lib/libxp_nuencryption.sl xp_nuhash.o \
/usr/lib/pa20_64/libstd_v2.a \
/usr/lib/pa20_64/libCsup_v2.a
chatr +dbg enable /home/jchamber/datasecure/lib/libxp_nuencryption.sl
Here is how we test:
SQL> @nuhash2
Library created.
Package created.
Package body created.
SQL> @testnuhash2
DECLARE
ERROR at line 1:
ORA-28576: lost RPC connection to external procedure agent
ORA-06512: at "JCHAMBER.XP_NUENCRYPTION", line 0
ORA-06512: at line 3
Now, if i use classic C++ (aCC -AP) it works. The trouble is, we have a lot of code that uses the Standard C++ library and we don't have the time to port it back to classic C++.
The problem seems to be with an incompatibility with the standard C++ library. What is the magic potion of linker and/or compiler switches that would enable my extended procedures to use the standard C++ library?
Here is the environment we are using:
Oracle 9i (64-bit)
HP UX 11.11
