Re: Unusual try...catch behavior

In my program I have following C++ function:

===========================
extern void
getUserEmailAddress (
   std::string &userId,
   stringSet &emailAddresses
   )
{
   int ifail = ITK_ok ;

   tag_t userTag = NULLTAG ;
   if ((ifail = SA_find_user (userId.c_str (), &userTag)) != ITK_ok)
   {
       throw (SOTTcEngException (ifail)) ;
   }
   if (userTag == NULLTAG)
   {
       throw (SOTTcEngException (SA_finding_user)) ;
   }

   getUserEmailAddress (userTag, emailAddresses) ;
}
===========================

I expect that if the function "SA_find_user" returns ITK_ok, but
userTag is still NULLTAG, function should throw an exception
"SOTTcEngException (SA_finding_user)".

But what I have seen is that function does throw an exception, but
instead
of coming out of the function and entering catch block of the calling
function, execution continues to next statement of
"getUserEmailAddress (userTag, emailAddresses)"...as if that throw
statement is an empty statement.

I have seen this behavior wheather I am debugging through visual
studio or executing normally without debugging.

Why program execution continues after throwing an exception? Am I
missing something in the code?
