How to return object type from external c procedure ?

Question

Hello all,
I'm trying for the first time to return an object type as the return value of an external stored procedure (in C ).
I don't have any issue to use an object type parameter for the function but not to return one to the caller.
each time I try I get "ORA-03113: end-of-file on communication channel" and the connection is dropped.
Thanks for any help,

here is the code :
=> object type
SQL>create or replace type address as object ( age number, salary float );
=> address typ file
CASE=SAME
TYPE address as address
=> building the dependences structures.
$>ott userid=scott/tiger intype=address.type code=c hfile=address.h
=> the package description
create or replace package userTypeDefined_PKG
is
function getAddr( addr address ) return address;
end;
create or replace package body userTypeDefined_PKG
is
function getAddr( addr address ) return address
AS LANGUAGE C
NAME "addr"
LIBRARY userTypeDefinedLib
WITH CONTEXT
PARAMETERS
( CONTEXT,
addr,
addr INDICATOR STRUCT ,
return address,
return INDICATOR STRUCT
end;
=> The C code for the library in
address* addr(OCIExtProcContext ctx, address address_obj, address_ind address_obj_ind, address_ind ret_ind){
unsigned int tt;
OCIEnv *envh;
OCIError *errh;
OCISvcCtx *svch;
sword err;
address* ret = NULL;
int inum = 69;
float fnum = 12.34;
/* get OCI Environment */
err = OCIExtProcGetEnv(ctx, &envh, &svch, &errh) ;
/* allocate space for return sturcture*/
ret = (address *)OCIExtProcAllocCallMemory(ctx, sizeof(address));
/* set the AGE value */
if ( OCINumberFromInt ( errh, &inum, sizeof(inum), OCI_NUMBER_SIGNED, &(ret->AGE) ) == OCI_ERROR )
OCIExtProcRaiseExcp(ctx,(int)1476); // raise 1476 is fail
/* set the SALARY value */
if ( OCINumberFromReal ( errh, &fnum, sizeof(fnum), &(ret->SALARY) ) == OCI_ERROR )
OCIExtProcRaiseExcp(ctx,(int)1477);// raise 1477 is fail
// set the indicators for the structure as not null
ret_ind->atomic = OCIIND_NOTNULL;
ret_ind->AGE = OCI_IND_NOTNULL;
ret_ind->SALARY = OCI_IND_NOTNULL;
return (ret);
}

The return indicator should be declared as double pointer, and need to be allocated in the function body.
