[Trilinos-Users] aliasing in Epetra/Ifpack/NOX

I'm experiencing some trouble with user-defined preconditioners.
Is it possible that a call to Epetra_Operator::ApplyInverse(x,y) is
actually called with the same vector, ApplyInverse(x,x)? Do I have to
check for that case in my implementations? I know that the C++ standard
allows aliasing, but I still favor the fortran way...
