[Trilinos-Users] Teuchos::RCP behavior

[Bartlett, Roscoe A.]

Please carefully read section "5.11.6 Limitations of debug-mode runtime checking" in:

   http://www.ornl.gov/~8vt/TeuchosMemoryManagementSAND.pdf

If you construct your own objects on the stack there is nothing the Teuchos Memory Management classes can do to find invalid usage.

Subject: [Trilinos-Users] Teuchos::RCP behavior



I've implemented a very simple test code:

void assign(Teuchos::RCP<UInt> & P)
{
  UInt i = 4;
  P = Teuchos::rcpFromRef(i);
  cout << *P << endl;
}

int main(int argc, char *argv[])
{
  Teuchos::RCP<UInt> P;
  assign(P);

  cout << *P << endl;
  cout << "count: " << P.total_count() << endl;
}

I think that this is a non-correct usage of the RCP class, since a temporary reference is passed to P. In fact I get the following output:

4
0
count: 1

However even I have built Trilinos using
-D Teuchos_ENABLE_DEBUG:BOOL=ON \
-D Teuchos_ENABLE_DEBUG_RCP_NODE_TRACING:BOOL=ON \
no exception is thrown. Am I missing something?

Thank you very much.
Andrea Villa.
