C2712: Cannot use __try in functions that require object unwinding

Question

I am migrating a software writen with VC++ 6.0 to VS 2010/VC++2010. and I have a project which does not compile in Debug mode. I have:

LBSC_AppUserInfoList *          
LBSC_Session::GetUsersInfo( const LBSC_Ticket *pTicket )
{
    TSROut_GetUsersInfo sOut;
    C_Buffer            *pcbRet = NULL;
    TSRIn_TicketPar     InPar;
//...
    ClntFree( (void *)sOut.szBuffer );  // dealoca o que veio do RPC

        return( pList );
} // C2712 - Cannot use __try in functions that require object unwinding

and I haven´t any mention to __try

do you undestand?

Answer 1

It seems like the most likely problem here is that ClntFree is actually a macro that expands out to use an SEH __try block. Nothing else on the surface seems like it would make sense as a macro and a macro seems like the most likely cause here.

Have you looked at the definition of ClntFree to see if it's a macro or not?
