Hello,
I tried the following:
Query(Connection *c ,bool te = true):
std::ostream(std::_Noinit),
OptionalExceptions(te),
Locakable(false),
def(this),
conn_(c),
success_(false)
{
printf("Enter Query(connection * c,bool
te=true\n");
init(&sbuffer);
success_ = true;
}
Ok what I see now is that when the applications stops
no leak occurs when using purify. However, the
application is still growing during runtime when each
query action is made. This worries me. It still looks
like its not freeing up the memory after the query has
completed only when the application is torn down.
Any insight would of course be appreciated.
Thanks,
Garyc
