Program crashes in OCI calls

Question

All,
The program has set of OCI datatype converion calls from C native to Oracle types. The program crashes in OCI calls specifically in OCINumberFromReal. Below is the stack for the core dump created.
In call to OCINumberFromReal, when it refences lnxren function, the program crashes with SIGBUS.
The application in on solaris 10 and Oracle 11g.

Please suggest on how to resolve this.
Thanks in advance

hi Nikeda,
I replaced the sizeof(double) to DBL_DIG/FLT_DIG constant, now the program doesn't crashes but the conversion is not happening properly.
The result of any number after conversion is "0".
Any suggestions, Thanks in advance .. below is the code snippet u asked for ..
class ABC
double qty ;
ott structure
struct abc_ott
OCINumber qty ;
// pro*c code
EXEC SQL BEGIN DECLARE SECTION ;
abc_ott * abc_ott_inst ;
EXEC SQL END DECLARE SECTION ;
EXEC SQL ALLOCATE :abc_ott_inst ;
ABC * abc = new ABC ;
abc->qty = 100.0 ;
OCINumberFromReal(ociError, &abc->qty, (uword)sizeof(double), &abc_ott_inst->qty ) ;
// call with DBL_DIG
OCINumberFromReal(ociError, &abc->qty, DBL_DIG, &abc_ott_inst->qty ) ;
