This the declaration

--FBUDF_API ISC_TIMESTAMP* addDay(ISC_TIMESTAMP* v, int ndays)
declare external function addDay
timestamp, int
returns timestamp
entry_point 'addDay' module_name 'fbudf';

I have looked at the source code also. There is nothing, which can
cause memory leak.

FBUDF_API ISC_TIMESTAMP* addDay(ISC_TIMESTAMP* v, const int& ndays)
{
v->timestamp_date += ndays;
return v;
}

Is there a way that somebody else can do a test for this ??
